Cognitive Decision Support for Industrial Product Life Cycles: A Position Paper

Proceedings of the Eleventh International Conference on Advanced Cognitive Technologies and Applications (COGNITIVE 2019), Marta Franova, Charlotte Sennersten, Jayfus T. Doswell, IARIA, Venice, Italy, 2019

Konferenz
Current trends in manufacturing lead to more intelligent products, produced in global supply chains in shorter cycles, taking more and complex requirements into account. To manage this increasing complexity, cognitive decision support systems, building on data analytic approaches and focusing on the product life cycle, stages seem a promising approach. With two high-tech companies (world market leader in their domains) from Austria, we are approaching this challenge and jointly develop cognitive decision support systems for three real world industrial use cases. Within this position paper, we introduce our understanding of cognitive decision support and we introduce three industrial use cases, focusing on the requirements for cognitive decision support. Finally, we describe our preliminary solution approach for each use case and our next steps.

Finding traces of self-regulated learning in activity streams

ACM Conference on Learning Analytics and Knowledge, LAK , ACM, ACM, 2018

Konferenz
This paper aims to identify self-regulation strategies from students' interactions with the learning management system (LMS). We used learning analytics techniques to identify metacognitive and cognitive strategies in the data. We define three research questions that guide our studies analyzing i) self-assessments of motivation and self regulation strategies using standard methods to draw a baseline, ii) interactions with the LMS to find traces of self regulation in observable indicators, and iii) self regulation behaviours over the course duration. The results show that the observable indicators can better explain self-regulatory behaviour and its influence in performance than preliminary subjective assessments.

Realising the European open science cloud

European Union, 2016

The European Open Science Cloud (EOSC) aims to accelerate and support the current transition to more effective Open Science and Open Innovation in the Digital Single Market. It should enable trusted access to services, systems and the re-use of shared scientific data across disciplinary, social and geographical borders. This report approaches the EOSC as a federated environment for scientific data sharing and re-use, based on existing and emerging elements in the Member States, with light-weight international guidance and governance, and a large degree of freedom regarding practical implementation.

Learning analytics for workplace and professional learning

Proceedings of the Sixth International Conference on Learning Analytics & Knowledge, ACM, 2016

Konferenz
Recognizing the need for addressing the rather fragmented character of research in this field, we have held a workshop on learning analytics for workplace and professional learning at the Learning Analytics and Knowledge (LAK) Conference. The workshop has taken a broad perspective, encompassing approaches from a number of previous traditions, such as adaptive learning, professional online communities, workplace learning and performance analytics. Being co-located with the LAK conference has provided an ideal venue for addressing common challenges and for benefiting from the strong research on learning analytics in other sectors that LAK has established. Learning Analytics for Workplace and Professional Learning is now on the research agenda of several ongoing EU projects, and therefore a number of follow-up activities are planned for strengthening integration in this emerging field.

Visualization of co-readership patterns from an online reference management system

Journal of Informetrics, Elsevier, NULL, 2015

Journal
In this paper, we analyze the adequacy and applicability of readership statistics recorded in social reference management systems for creating knowledge domain visualizations. First, we investigate the distribution of subject areas in user libraries of educational technology researchers on Mendeley. The results show that around 69% of the publications in an average user library can be attributed to a single subject area. Then, we use co-readership patterns to map the field of educational technology. The resulting visualization prototype, based on the most read publications in this field on Mendeley, reveals 13 topic areas of educational technology research. The visualization is a recent representation of the field: 80% of the publications included were published within ten years of data collection. The characteristics of the readers, however, introduce certain biases to the visualization. Knowledge domain visualizations based on readership statistics are therefore multifaceted and timely, but it is important that the characteristics of the underlying sample are made transparent.

Unleashing semantics of research data

Specifying Big Data Benchmarks, Springer, Berlin, Heidelberg, 2014

Buch
Research depends to a large degree on the availability and quality of primary research data, i.e., data generated through experiments and evaluations. While the Web in general and Linked Data in particular provide a platform and the necessary technologies for sharing, managing and utilizing research data, an ecosystem supporting those tasks is still missing. The vision of the CODE project is the establishment of a sophisticated ecosystem for Linked Data. Here, the extraction of knowledge encapsulated in scientific research paper along with its public release as Linked Data serves as the major use case. Further, Visual Analytics approaches empower end users to analyse, integrate and organize data. During these tasks, specific Big Data issues are present.

Proceedings of {ECTEL} meets {ECSCW} 2013, the Workshop on Collaborative Technologies for Working and Learning, Paphos, Cyprus, September, 21, 2013

CEUR Workshop Proceedings, 2013

Konferenz
With this workshop, we brought together the European communities of technology-enhanced learning, which typically meets at the ECTEL, and of computer-supported cooperative work, which typically meets at the ECSCW. While the ECTEL community has traditionally focused on technology support for learning, be it in formal learning environments like schools, universities, etc. or in informal learning environments like workplaces, the ECSCW community has traditionally investigated how computers can and do mediate and influence collaborative work, in settings as diverse as the typical “gainful employment” situations, project work within university courses, volunteer settings in NGOs etc. Despite overlapping areas of concerns, the two communities are also exploiting different theories and methodological approaches. Within this workshop, we discussed issues that are relevant for both communities, and have the potential to contribute to a more lively communication between both communities.

iScope - Viewing Biosignals on Mobile Devices.

Joint International Conference on Pervasive Computing and the Networked World, Qiaohong Zu, Bo Hu, Atilla Elçi , Springer, 2013

Journal
We developed an iOS based application called iScope to monitor biosignals online. iScope is able to receive different signal types via a wireless network connection and is able to present them in the time or the frequency domain. Thus it is possible to inspect recorded data immediately during the recording process and detect potential artifacts early without the need to carry around heavy equipment like laptops or complete PC workstations. The iScope app has been tested during various measurements on the iPhone 3GS as well as on the iPad 1 and is fully functional.

Linked Data Query Wizard: A Tabular Interface for the Semantic Web

ESWC 2013, LNCS 7882, P. Cimiano et al., Springer, Heidelberg, 2013

Konferenz
Linked Data has become an essential part of the Semantic Web. A lot of Linked Data is already available in the Linked Open Data cloud, which keeps growing due to an influx of new data from research and open government activities. However, it is still quite difficult to access this wealth of semantically enriched data directly without having in-depth knowledge about SPARQL and related semantic technologies. In this paper, we present the Linked Data Query Wizard, a prototype that provides a Linked Data interface for non-expert users, focusing on keyword search as an entry point and a tabular interface providing simple functionality for filtering and exploration.

Head Start: Improving Academic Literature Search with Overview Visualizations based on Readership Statistics

Web Science 2013, 2013

Konferenz
At the beginning of a scientific study, it is usually quite hardto get an overview of a research field. We aim to addressthis problem of classic literature search using web data. Inthis extended abstract, we present work-in-progress on aninteractive visualization of research fields based on readershipstatistics from the social reference management systemMendeley. To that end, we use library co-occurrences as ameasure of subject similarity. In a first evaluation, we findthat the visualization covers current research areas withineducational technology but presents a view that is biasedby the characteristics of readers. With our presentation, wehope to elicit feedback from the Websci’13 audience on (1)the usefulness of the prototype, and (2) how to overcomethe aforementioned biases using collaborative constructiontechniques.

Tag-based algorithms can predict human ratings of which objects a picture shows

Multimedia Tools and Applications, Springer US, 2012

Journal
Collaborative tagging platforms allow users to describe resources with freely chosen keywords, so called tags. The meaning of a tag as well as the precise relation between a tag and the tagged resource are left open for interpretation to the user. Although human users mostly have a fair chance at interpreting this relation, machines do not. In this paper we study the characteristics of the problem to identify descriptive tags, i.e. tags that relate to visible objects in a picture. We investigate the feasibility of using a tag-based algorithm, i.e. an algorithm that ignores actual picture content, to tackle the problem. Given the theoretical feasibility of a well-performing tag-based algorithm, which we show via an optimal algorithm, we describe the implementation and evaluation of a WordNet-based algorithm as proof-of-concept. These two investigations lead to the conclusion that even relatively simple and fast tag-based algorithms can yet predict human ratings of which objects a picture shows. Finally, we discuss the inherent difficulty both humans and machines have when deciding whether a tag is descriptive or not. Based on a qualitative analysis, we distinguish between definitional disagreement, difference in knowledge, disambiguation and difference in perception as reasons for disagreement between raters.

Seeing What the System Thinks You Know - Visualizing Evidence in an Open Learner Model

Proceedings of the 2nd International Conference on Learning Analytics and Knowledge, ACM, Canada, 2012

User knowledge levels in adaptive learning systems can be assessed based on user interactions that are interpreted as Knowledge Indicating Events (KIE). Such an approach makes complex inferences that may be hard to understand for users, and that are not necessarily accurate. We present MyExperiences, an open learner model designed for showing the users the inferences about them, as well as the underlying data. MyExperiences is one of the first open learner models based on tree maps. It constitutes an example of how research into open learner models and information visualization can be combined in an innovative way.

Exploiting the User Interaction Context for Automatic Task Detection

Applied Artificial Intelligence, Taylor & Francis Group, 2012

Journal
Detecting the task a user is performing on his/her computer desktop is important in order to provide him/her with contextualized and personalized support. Some recent approaches propose to perform automatic user task detection by means of classifiers using captured user context data. In this paper we improve on that by using an ontology-based user interaction context model that can be automatically populated by (1) capturing simple user interaction events on the computer desktop and (2) applying rule-based and information extraction mechanisms. We present evaluation results from a large user study we have carried out in a knowledge-intensive business environment, showing that our ontology-based approach provides new contextual features yielding good task-detection performance. We also argue that good results can be achieved by training task classifiers “offline” on user context data gathered in laboratory settings. Finally, we isolate a combination of contextual features that present a significantly better discriminative power than classical ones.

The role of Reflection in Maturing Organizational Know-how

Proceedings of the 1st European Workshop on Awareness and Reflection in Learning Networks, Palermo, Italy, September 21, 2011, Reinhardt, W., Ullmann, T. D., Scott, P., Pammer, V., Conlan, O., Berlanga, A., 2011

Konferenz
The Knowledge Maturing Phase Model has been presented as a model aligning knowledge management and organizational learning. The core argument underlying the present paper is that maturing organizational knowhow requires individual and collaborative reflection at work. We present an explorative interview study that analyzes reflection at the workplace in four organizations in different European countries. Our qualitative findings suggest that reflection is not equally self-evident in different settings. A deeper analysis of the findings leads to the hypothesis that different levels of maturity of processes come along with different expectations towards the workers with regard to compliance and flexibility, and to different ways of how learning at work takes place. Furthermore, reflection in situations where the processes are in early maturing phases seems to lead to consolidation of best practice, while reflection in situations where processes are highly standardized may lead to a modification of these standard processes. Therefore, in order to support the maturing of organizational know-how by providing reflection support, one should take into account the degree of standardisation of the processes in the target group.

A Preliminary Study on Interruptibility Detection based on Location and Calendar Information

Third Workshop on Context-Systems Design, Evaluation and Optimisation (CoSDEO) 2011, December 6th - 8th, Copenhagen, Denmark, 2011., 2011

Journal
Modern communication technology-such as mobile phonesincreases our level of availability, but also raises the risk of being inappropriately interrupted. In this paper, we present our on-going research on automatically detecting a user’s interruptibility. This is the first step towards (i) contextualizing the modus of message notification, ie making the notification more or less attention-grabbing, and (ii) contextualizing message ranking, ie, prioritizing messages according to their relevance for the user’s current level of activity. We describe our approach of automatically detecting a user’s interruptibility based on location and calendar information. Both kinds of data are easily available in a mobile setting using smartphones. Second, we present a preliminary study that evaluates (i) whether GPS information is available sufficiently for our purpose in a real-world setting, and (ii) whether the computed interruptibility corresponds to a user’s own perception of interruptibility.

Motivation and User Acceptance of Using Physiological Data to Support Individual Reflection

2nd International Workshop on Motivation and Affective Aspects in Technology Enhanced Learning (MATEL 2011), co-located with the Sixth European Conference on Technology Enhanced Learning (ECTEL 2011), 2011

While research comes up with new sensors and physiologicaldata is gaining more attention in private usage, sensors play no role inprofessional learning. In this paper we shed light on the motivation touse physiological sensors in the workplace. Three user studies have beenconducted in five companies to assess the motivation to (a) wear sensorsand (b) reflect on physiological data during work. Based on these studies,we show that workers would be willing to use physiological sensors, butthe benefit of the awareness about the own physiological state is oftennot clear or the usability of sensors is insufficient. Moreover, in stressprone professions like emergency care there are already successful copingstrategies in place. Introducing physiological sensors has to provide clearbenefits by offering solutions to act on this awareness and focus on thepracticability of the sensors.

An Ontology-Based Approach for Detecting Knowledge Intensive Tasks

Journal of Digital Information Management, Pichappan, P., Jacobs, D. , Digital Information Research Foundation, 2011

Journal
In the context detection field, an important challenge is automatically detecting the user's task, for providing contextualized and personalized user support. Several approaches have been proposed to perform task classification, all advocating the window title as the best discriminative feature. In this paper we present a new ontology-based task detection approach, and evaluate it against previous work. We show that knowledge intensive tasks cannot be accurately classified using only the window title. We argue that our approach allows classifying such tasks better, by providing feature combinations that can adapt to the domain and the degree of freedom in task execution.

On the Way to a Science Intelligence: Visualizing TEL Tweets for Trend Detection

Sixth European Conference on Technology Enhanced Learning (EC-TEL 2011), Springer, 2011

Konferenz
This paper presents an adaptable system for detecting trends based on the micro-blogging service Twitter, and sets out to explore to what extent such a tool can support researchers. Twitter has high uptake in the scientific community, but there is a need for a means of extracting the most important topics from a Twitter stream. There are too many tweets to read them all, and there is no organized way of keeping up with the backlog. Following the cues of visual analytics, we use visualizations to show both the temporal evolution of topics, and the relations between different topics. The Twitter Trend Detection was evaluated in the domain of Technology Enhanced Learning (TEL). The evaluation results indicate that our prototype supports trend detection but reveals the need for refined preprocessing, and further zooming and filtering facilities.

Evaluation of social media collaboration using task-detection methods

ECTEL 2011, Palermo, Italy, 20-23 September 2011, Springer, 2011

Konferenz
Collaboration using social media is a good way of jointly constructing knowledge. This study aims at better understanding collaborative knowledge construction processes by applying innovative (micro-)task detection approaches. We take a closer look at the interactions of a user with a shared digital artifact by analyzing the captured interaction data. The goal is to identify domain-independent interaction patterns, which can serve as indicators for knowledge development (operationalized as accommodation). We designed an empirical study under laboratory conditions that used our method. The applied task detection approach identified accommodation with a rate of 77.63% without resorting to textual features. This result instantiates an improvement as compared to a previous study in which the text in focus was identified as the feature with best discriminative power. We discuss our hypothesis that our method is independent from the used knowledge domain.

Research Practices on the Web in the Field of Technology Enhanced Learning

ACM Webscience Conference 2011, 2011

Journal
Recently, developments under the banners of Science/Research 2.0 have received a lot of attention in the scientific community. Along with Web 2.0 tools and technologies, a certain change in researcher practices can be observed. The study proposed for this paper was conducted to gain first insight into these practices among researchers in Technology Enhanced Learning (TEL). We conducted two focus groups with a total of 14 participants from the domains of knowledge management and e-learning. Only a limited amount of Science 2.0 practices were identified, mostly related to research design and publication. Potentials for support, however, exist in all steps of the TEL research process. We conclude that tools and technologies must either support existing practice to provide a benefit, or solve obvious shortcomings in existing practice.

Reflective Learning at Work - A Position and Discussion Paper

Proceedings of the 1st European Workshop on Awareness and Reflection in Learning Networks (ARNETS'11), Reinhardt, W., Ullmann, T., Scott, P., Pammer, V., Conlan, O., Berlanga, A., CEUR Workshop Proceedings, 2011

The relevance of reflection for learning has long been recognised,and there is a substantial body of theoretical work on reflection.However, many questions regarding reflection at the workplace are stillopen, especially regarding the actual occurrence of reflection in differentworkplaces, and the efficient support for reflection.In our ongoing work to examine the relevance of reflective learning atwork in various organisations and to design technological support, wehave collected and discussed existing literature on reflective learning.Within this paper, we discuss relevant and open issues in four majortopical areas that are relevant to the above research goal, namely (i) thereflection process , (ii) the various scopes of reflection such as individualand organisational learning, (iii) the context or setting in which reflectionmight take place and (iv) how we can facilitate and scaffold reflectionby means of technology. We aim to provide a basis for discussion and toillustrate that research on reflection, especially in the context of work, isfar from finished.

Context-Aware Recommendation for Work-Integrated Learning

Context and Semantics for Knowledge Management. Technologies for Personal Productivity, Warren, P., Davies, J., Simperl, E., Springer, 2011

Journal
Within this chapter we first outline the important role learning plays within knowledge work and its impact on productivity. As a theoretical background we introduce the paradigm of Work-Integrated Learning (WIL) which conceptualizes informal learning at the workplace and takes place tightly intertwined with the execution of work tasks. Based on a variety of in-depth knowledge work studies we identify key requirements for the design of work-integrated learning support. Our focus is on providing learning support during the execution of work tasks (instead of beforehand), within the work environment of the user (instead of within a separate learning system), and by repurposing content for learning which was not originally intended for learning (instead of relying on the expensive manual creation of learning material). In order to satisfy these requirements we developed a number of context-aware knowledge services. These services integrate semantic technologies with statistical approaches which perform well in the face of uncertainty. These hybrid knowledge services include the automatic detection of a user’s work task, the ‘inference’ of the user’s competencies based on her past activities, context-aware recommendation of content and colleagues, learning opportunities, etc. A summary of a 3 month in-depth summative workplace evaluation at three testbed sites concludes the chapter.

First experiences with a Science 2.0 infrastructure

2011

This deliverable reports on first usage experiences and evaluations of the STELLAR Science 2.0 Infrastructure. Usage experiences were available predominantly for the "mature" part of the infrastructure provided by standard Web 2.0 tools adapted to STELLAR needs. Evaluations are provided for newly developed tools. We first provide an overview of the whole STELLAR Science 2.0 Infrastructure and the relationships between the building blocks. While the individual building blocks already benefit researchers, the integration between them is the key for a positive usage experience. The publication meta data ecosystem for example provides researchers with an easy to retrieve set of TEL related data. Tools like the ScienceTable, Muse, the STELLAR latest publication widget, and the STELLAR BuRST search show already several scenarios of how to make use of this infrastructure. Especially a strong focus on anlytical tools based on publication and social media data seem useful. In order to highlight the relevance of the infrastructure to the individual capacitiy building activties within STELLAR, the usage experiences of individual building blocks are then reported with respect to Researcher Capacity (e.g. Deliverable Wikis, More! application), Doctoral Academy Capacity (e.g. DoCoP), Community Level Capacity (e.g TELeurope), and Leadership Capacity (e.g. Meeting of Minds, Podcast Series). Here we draw from 11 scientific papers published. The reader will find an overview of all these papers in the Appendix. Based on the usage experiences and evaluations we have identified a number of ideas which might be worth considering for future developments. For example, the experiences gained with the Deliverable Wikis show how the modification of the standard Wiki history can provide useful analytical insights into the collaboration of living deliverables and can return the focus on authorship (which is intentionally masked in Wikis, because of their strong notion on the product and not on authors). We conclude with main findings and an outlook on the development plan and evaluation plan which are currently being developed and which will influence D6.6. Particularly, we close with the notion of a Personal Research Environment (PRE) which draws from the concept of Personal Learning Environments (PLE).

dataTEL-Datasets for technology enhanced learning-White paper

Stellar Open Archive, 2011

The dataTEL white paper develop during the dataTEL workshop at the ARV2011. The workshop was motivated by the issue that very less educational datasets are publicly available in TEL, so that the outcomes of different TEL adaptive applications and recommender systems that support personalised learning are hardly comparable. In other domains like in e-commerce it is a common practise to use different datasets as benchmarks to evaluate recommender systems algorithms to make the results comparable (MovieLens, Book-Crossing, EachMovie dataset). So far, no universally valid knowledge exists in TEL on algorithm that can be successfully applied in a certain learning setting to personalise learning. Having a collection of datasets could be a first major step towards a theory of personalisation with in TEL that can be based on empirical experiments with verifiable and valid results.

Datasets for Technology Enhanced Learning

Alpine Rendez-Vous 2011, 2011

The workshop was motivated by the issue that very less educational datasets are publicly available in TEL, so that the outcomes of different TEL adaptive applications and recommender systems that support personalised learning are hardly comparable. In other domains like in e-commerce it is a common practise to use different datasets as benchmarks to evaluate recommender systems algorithms to make the results comparable (MovieLens, Book-Crossing, EachMovie dataset). So far, no universally valid knowledge exists in TEL on algorithm that can be successfully applied in a certain learning setting to personalise learning. Having a collection of datasets could be a first major step towards a theory of personalisation within TEL that can be based on empirical experiments with verifiable and valid results. Therefore, the main objective of the dataTEL workshop was to explore suitable datasets for TEL with a specific focus on recommender and adaptive information systems that can take advantage of these datasets. In this context, new challenges emerge like unclear legal protection rights and privacy issues, suitable policies and formats to share data, required preprocessing procedures and rules to create sharable datasets, common evaluation criteria for recommender systems in TEL and how a dataset driven future in TEL could look like.

A User Centered Approach for Quality Assessment in Social Systems

KMIS, 2011

Journal
Analyzing the meaning of quality in information systems has a long tradition. As a result of the increasing amount of user generated content on the web, addressing quality is more relevant than ever. Since information is produced and consumed by different people in various contexts the perception of quality is always closely tied to the users’ situation. This work proposes an approach for assessing quality in social systems with respect to the users’ current needs.

Providing Varying Degrees of Guidance for Work-Integrated Learning

Sustaining TEL: From Innovation to Learning and Practice, Proceedings of EC-TEL 2010, Wolpers, M., Kirschner, P. A., Scheffel, M., Lindstaedt, S. N., Dimitrova, V., Springer, 2010

Konferenz
We present a work-integrated learning (WIL) concept which aims atempowering employees to learn while performing their work tasks. Withinthree usage scenarios we introduce the APOSDLE environment whichembodies the WIL concept and helps knowledge workers move fluidly alongthe whole spectrum of WIL activities. By doing so, they are experiencingvarying degrees of learning guidance: from building awareness, over exposingknowledge structures and contextualizing cooperation, to triggering reflectionand systematic competence development. Four key APOSDLE components areresponsible for providing this variety of learning guidance. The challenge intheir design lies in offering learning guidance without being domain-specificand without relying on manually created learning content. Our three monthsummative workplace evaluation within three application organizationssuggests that learners prefer awarenss building functionalities and descriptivelearning guidance and reveals that they benefited from it.

Journal
When inferring a user’s knowledge state from naturally occurringinteractions in adaptive learning systems, one has to makes complexassumptions that may be hard to understand for users. We suggestMyExperiences, an open learner model designed for these specificrequirements. MyExperiences is based on some of the key design principles ofinformation visualization to help users understand the complex information inthe learner model. It further allows users to edit their learner models in order toimprove the accuracy of the information represented there.

Recommending Knowledgeable People in a Work-Integrated Learning System

1st Workshop on Recommender Systems for Technology Enhanced Learning (RecSysTEL 2010), 2010

Konferenz
According to studies into learning at work, interpersonal help seeking is the most important strategy of how people acquireknowledge at their workplaces. Finding knowledgeable persons, however, can often be difficult for several reasons. Expertfinding systems can support the process of identifying knowledgeable colleagues thus facilitating communication andcollaboration within an organization. In order to provide the expert finding functionality, an underlying user model is needed thatrepresents the characteristics of each individual user. In our article we discuss requirements for user models for the workintegratedlearning (WIL) situation. Then, we present the APOSDLE People Recommender Service which is based on anunderlying domain model, and on the APOSDLE User Model. We describe the APOSDLE People Recommender Service on thebasis of the Intuitive Domain Model of expert finding systems, and explain how this service can support interpersonal helpseeking at workplaces.

Just as testing is an integral part of software engineering, so is ontologyevaluation an integral part of ontology engineering. We haveimplemented automated support for formative ontology evaluationbased on the two principles of i) checking for compliance withmodelling guidelines and ii) reviewing entailed statements in MoKi,a wiki based ontology engineering environment. These principlesexist in state of the art literature and good ontology engineering andevaluation practice, but have not so far been widely integrated intoontology engineering tools.

Content Recommendation in APOSDLE using the Associative Network

Journal of Universal Computer Science, 2010

Journal
One of the success factors of Work Integrated Learning (WIL) is to provide theappropriate content to the users, both suitable for the topics they are currently working on, andtheir experience level in these topics. Our main contributions in this paper are (i) overcomingthe problem of sparse content annotation by using a network based recommendation approachcalled Associative Network, which exploits the user context as input; (ii) using snippets for notonly highlighting relevant parts of documents, but also serving as a basic concept enabling theWIL system to handle text-based and audiovisual content the same way; and (iii) using the WebTool for Ontology Evaluation (WTE) toolkit for finding the best default semantic similaritymeasure of the Associative Network for new domains. The approach presented is employed inthe software platform APOSDLE, which is designed to enable knowledge workers to learn atwork.

Studying the Factors Influencing Automatic User Task Detection on the Computer Desktop

Sustaining TEL: From Innovation to Learning and Practice, Lecture Notes in Computer Science, Springer, 2010

. Supporting learning activities during work has gained momentum fororganizations since work-integrated learning (WIL) has been shown to increaseproductivity of knowledge workers. WIL aims at fostering learning at the workplace,during work, for enhancing task performance. A key challenge for enablingtask-specific, contextualized, personalized learning and work support is to automaticallydetect the user’s task. In this paper we utilize our ontology-based usertask detection approach for studying the factors influencing task detection performance.We describe three laboratory experiments we have performed in twodomains including over 40 users and more than 500 recorded task executions.The insights gained from our evaluation are: (i) the J48 decision tree and Na¨ıveBayes classifiers perform best, (ii) six features can be isolated, which providegood classification accuracy, (iii) knowledge-intensive tasks can be classified aswell as routine tasks and (iv) a classifier trained by experts on standardized taskscan be used to classify users’ personal tasks.

CEUR Workshop Proceedings, CEUR-WS, 2010

Research2.0 is in essence a Web2.0 approach to how we do research. Research2.0 creates conversations between researchers, enables them to discuss their findings and connects them with others. Thus, Research2.0 can accelerate the diffusion of knowledge.ChallengesAs concluded during the workshop, at least four challenges are vital for future research.The first area is concerned with availability of data. Access to sanitized data and conventions on how to describe publication-related metadata provided from divergent sources are enablers for researchers to develop new views on their publications and their research area. Additional, social media data gain more and more attention. Reaching a widespread agreement about this for the field of technology-enhanced learning would be already a major step, but it is also important to focus on the next steps: what are success-critical added values driving uptake in the research community as a whole?The second area of challenges is seen in Research 2.0 practices. As technology-enhanced learning is a multidisciplinary field, practices developed in one area could be valuable for others. To extract the essence of successful multidisciplinary Research 2.0 practice though, multidimensional and longitudinal empirical work is needed. It is also an open question, if we should support practice by fostering the usage of existing tools or the development of new tools, which follow Research 2.0 principles. What makes a practice sustainable? What are the driving factors?The third challenge deals with impact. What are criteria of impact for research results (and other research artefacts) published on the Web? How can this be related to the publishing world appearing in print? Is a link equal to a citation or a download equal to a subscription? Can we develop a Research 2.0 specific position on impact measurement? This includes questions of authority, quality and re-evaluation of quality, and trust.The tension between openness and privacy spans the fourth challenge. The functionality of mash-ups often relies on the use of third-party services. What happens with the data, if this source is no longer available? What about hidden exchange of data among backend services?

A science 2.0 infrastructure for technology-enhanced learning

Computer Science Education, 2010

Journal
Science 2.0 is a rather young concept and despite its short historyalready induced numerous controversial positions, oscillating between newtechnologies and new practices. Even though many TEL researchers already useScience 2.0 tools, although not always labeled as such, there is no commonlyshared practice and tools in use. Within this paper, we investigate the conceptof Science 2.0 and propose an embracing definition. From there we investigateexisting practice with pilot studies and propose a framework for further indepthstudy and elicitation of Science 2.0 practices of technology-enhancedlearning researchers. Furthermore, we propose a mash-up architecture andconcrete infrastructure to leverage Science 2.0 practice and technologies in ourfield, including the proposal of a publication feed format, a retrieval API, andthe provision of an initial set of data sources and services. We illustrate the useof this infrastructure with several Science 2.0 application examples, therebydemonstrating the strength of this infrastructure and architecture.

An associative and adaptive network model for information retrieval in the Semantic Web

Progressive Concepts for Semantic Web Evolution: Applications and Developments, IGI Global, 2010

Buch
While it is agreed that semantic enrichment of resources would lead to better search results, at present the low coverage of resources on the web with semantic information presents a major hurdle in realizing the vision of search on the Semantic Web. To address this problem, this chapter investigates how to improve retrieval performance in settings where resources are sparsely annotated with semantic information. Techniques from soft computing are employed to find relevant material that was not originally annotated with the concepts used in a query. The authors present an associative retrieval model for the Semantic Web and evaluate if and to which extent the use of associative retrieval techniques increases retrieval performance. In addition, the authors present recent work on adapting the network structure based on relevance feedback by the user to further improve retrieval effectiveness. The evaluation of new retrieval paradigms - such as retrieval based on technology for the Semantic Web - presents an additional challenge since no off-the-shelf test corpora exist. Hence, this chapter gives a detailed description of the approach taken to evaluate the information retrieval service the authors have built.

On the feasibility of a tag-based approach for deciding which objects a picture shows: An empirical study

Semantic Multimedia. 4th International Conference on Semantic and Digital Media Technologies, SAMT 2009 Graz, Austria, December 2-4, 2009 Proceedings, Springer, 2009

Konferenz
Many online platforms allow users to describe resources withfreely chosen keywords, so called tags. The specific meaning of a tag aswell as its specific relation to the tagged resource are left open for interpretationto the user. Although human users mostly have a fair chance atinterpreting it, machines do not. An algorithmic approach for identifyingdescriptive tags however could prove useful for intelligent search for picturesand providing first-cut overviews over tagged picture repositories.In this paper we investigate the characteristics of the problem to decidewhich tags describe visible entities on a given picture. Based on a systematicuser study, we are able to discuss in detail the problems involvedfor both humans and machines when identifying descriptive tags. Furthermore,we investigate the general feasibility of developing a tag-basedalgorithm tackling this question. Finally, a concrete implementation andits evaluation are presented.

Machine Learning based Work Task Classification

Journal of Digital Information Management, 2009

Journal
Increasing the productivity of a knowledgeworker via intelligent applications requires the identification ofa user’s current work task, i.e. the current work context a userresides in. In this work we present and evaluate machine learningbased work task detection methods. By viewing a work taskas sequence of digital interaction patterns of mouse clicks andkey strokes, we present (i) a methodology for recording thoseuser interactions and (ii) an in-depth analysis of supervised classificationmodels for classifying work tasks in two different scenarios:a task centric scenario and a user centric scenario. Weanalyze different supervised classification models, feature typesand feature selection methods on a laboratory as well as a realworld data set. Results show satisfiable accuracy and high useracceptance by using relatively simple types of features.

Work-integrated learning (WIL) poses unique challenges for usermodel design: on the one hand users’ knowledge levels need to be determinedbased on their work activities – testing is not a viable option; on the other handusers do interact with a multitude of different work applications – there is nocentral learning system. This contribution introduces a user model and correspondingservices (based on SOA) geared to enable unobtrusive adaptabilitywithin WIL environments. Our hybrid user model services interpret usage datain the context of enterprise models (semantic approaches) and utilize heuristics(scruffy approaches) in order to determine knowledge levels, identify subjectmatter experts, etc. We give an overview of different types of user model services(logging, production, inference, control), provide a reference implementationwithin the APOSDLE project, and discuss early evaluation results.

Detecting Real User Tasks by Training on Laboratory Contextual Attention Metadata

Proceedings of Exploitation User Attention Metadata (EUAM '09) held at Informatik '09, 2009

Konferenz
Detecting the current task of a user is essential for providing her with contextualizedand personalized support, and using Contextual Attention Metadata (CAM)can help doing so. Some recent approaches propose to perform automatic user task detectionby means of task classifiers using such metadata. In this paper, we show thatgood results can be achieved by training such classifiers offline on CAM gathered inlaboratory settings. We also isolate a combination of metadata features that present asignificantly better discriminative power than classical ones.

Revision support for modeling tasks, topics and skills

Proceedings of I-SEMANTICS ’09, 5th International Conference on Semantic Systems, Paschke, A., Weigand, H., Behrendt, W., Tochtermann, K., Pellegrini, T., 2009

Konferenz
Whatever purpose models are created for, they need to be evaluated inorder to ensure that they will serve their intended use. Unfortunately, model evaluationis a significant effort and no standard clear-cut evaluation methodology exists today.In this work we introduce our approach of distributing the evaluation effort over thewhole modeling process. This is achieved by providing (partly automated) feedbackon the models in different stages of development. We illustrate our approach based onthe specific goal of modeling tasks, topics and skills for the adaptive work-integratedlearning system APOSDLE.

UICO: An Ontology-Based User Interaction Context Model for Automatic Task Detection on the Computer Desktop

Proceedings of the Context Information and Ontology (CIAO2009) workshop as part of the ESWC 2009, Gomez-Perez, J. M., Haase, P., Tilly, M., Warren, P., ACM, 2009

Konferenz
‘Understanding context is vital’ [1] and ‘context is key’ [2]signal the key interest in the context detection field. Oneimportant challenge in this area is automatically detectingthe user’s task because once it is known it is possible tosupport her better. In this paper we propose an ontologybaseduser interaction context model (UICO) that enhancesthe performance of task detection on the user’s computerdesktop. Starting from low-level contextual attention metadatacaptured from the user’s desktop, we utilize rule-based,information extraction and machine learning approaches toautomatically populate this user interaction context model.Furthermore we automatically derive relations between themodel’s entities and automatically detect the user’s task.We present evaluation results of a large-scale user study wecarried out in a knowledge-intensive business environment,which support our approach.

Enterprise modelling focuses on the construction of a structureddescription, the so-called enterprise model, which represents aspectsrelevant to the activity of an enterprise. Although it has becomeclearer recently that enterprise modelling is a collaborative activity, involvinga large number of people, most of the enterprise modelling toolsstill only support very limited degrees of collaboration. Within thiscontribution we describe a tool for enterprise modelling, called MoKi(MOdelling wiKI), which supports agile collaboration between all differentactors involved in the enterprise modelling activities. MoKi is basedon a Semantic Wiki and enables actors with different expertise to developan enterprise model not only using structural (formal) descriptions butalso adopting more informal and semi-formal descriptions of knowledge.

Automatic Image Annotation using Visual Conent and Folksonomies

Multimedia Tools and Applications, Springer US, 2009

Journal
Automatic image annotation is an important and challenging task, andbecomes increasingly necessary when managing large image collections. This paperdescribes techniques for automatic image annotation that take advantage of collaborativelyannotated image databases, so called visual folksonomies. Our approachapplies two techniques based on image analysis: First, classification annotates imageswith a controlled vocabulary and second tag propagation along visually similar images.The latter propagates user generated, folksonomic annotations and is thereforecapable of dealing with an unlimited vocabulary. Experiments with a pool of Flickrimages demonstrate the high accuracy and efficiency of the proposed methods in thetask of automatic image annotation. Both techniques were applied in the prototypicaltag recommender “tagr”.

While it is agreed that semantic enrichment of resources wouldlead to better search results, at present the low coverage of resources onthe web with semantic information presents a major hurdle in realizing thevision of search on the Semantic Web. To address this problem we investigatehow to improve retrieval performance in a setting where resources aresparsely annotated with semantic information. We suggest employing techniquesfrom associative information retrieval to find relevant material, whichwas not originally annotated with the concepts used in a query. We presentan associative retrieval service for the Semantic Desktop and evaluate if theuse of associative retrieval techniques increases retrieval performance.Evaluation of new retrieval paradigms, as retrieval in the Semantic Web oron the Semantic Desktop, presents an additional challenge as no off-the-shelftest corpora for evaluation exist. Hence we give a detailed description of the

Analysis of Machine Learning Techniques for Context Extraction

Proceedings of 2008 International Conference on Digital Information Management (ICDIM08), IEEE Computer Society Press, 2008

Konferenz
’Context is key’ conveys the importance of capturing thedigital environment of a knowledge worker. Knowing theuser’s context offers various possibilities for support, likefor example enhancing information delivery or providingwork guidance. Hence, user interactions have to be aggregatedand mapped to predefined task categories. Withoutmachine learning tools, such an assignment has to be donemanually. The identification of suitable machine learningalgorithms is necessary in order to ensure accurate andtimely classification of the user’s context without inducingadditional workload.This paper provides a methodology for recording user interactionsand an analysis of supervised classification models,feature types and feature selection for automatically detectingthe current task and context of a user. Our analysisis based on a real world data set and shows the applicabilityof machine learning techniques.

Applying Scruffy Methods to Enable Work-integrated Learning

The European Journal of the Informatics Professional, 2008

Journal
This contribution introduces the concept of work-integrated learning which distinguishes itself from traditional e-Learning in that it provides learning support (i) during work task execution and tightly contextualized to the work context,(ii) within the work environment, and (iii) utilizes knowledge artefacts available within the organizational memory for learning. We argue that in order to achieve this highly flexible learning support we need to turn to" scruffy" methods (such as associative retrieval, genetic algorithms, Bayesian and other probabilistic methods) which can provide good results in the presence of uncertainty and the absence of fine-granular models. Hybrid approaches to user context determination, user profile management, and learning material identification are discussed and first results are reported.

A Socio-Technical Approach towards Supporting Intra-Organizational Collaboration

Proceedings of the European Conference on Technology Enhanced Learning (ECTEL) 2008, Maastricht, The Netherlands, September 16-19, Springer, 2008

Konferenz
Knowledge work in companies is increasingly carried out by teams of knowledge workers. They interact within and between teams with the common goal to acquire, apply, create and share knowledge. In this paper we propose a socio-technical model to support intra-organizational collaboration which specifically takes into account the social and collaborative nature of knowledge work. Our aim is to support in particular the efficiency of collaborative knowledge work processes through an automated recommendation of collaboration partners and collaboration media. We report on the theoretical as well as practical aspects of such a socio-technical model.

Knowledge Services for Work-integrated Learning

Proceedings of the European Conference on Technology Enhanced Learning (ECTEL) 2008, Maastricht, The Netherlands, September 16-19, Springer, 2008

Konferenz
In order to support work-integrated learning scenarios task- andcompetency-aware knowledge services are needed. In this paper we introducethree key knowledge services of the APOSDLE system and illustrate how theyinteract. The context determination daemon observes user interactions andinfers the current work task of the user. The user profile service uses theidentified work tasks to determine the competences of the user. And finally, theassociative retrieval service utilizes both the current work task and the inferredcompetences to identify relevant (learning) content. All of these knowledgeservices improve through user feedback.

The paper suggests a way to support work-integrated learning for knowledge workwhich poses a great challenge for current research and practice. We first present a WorkplaceLearning Context Model which has been derived by analyzing knowledge work and the knowledgesources used by knowledge workers. The model specifies an integrative view on knowledgeworkers’ work environment by connecting learning, work and knowledge spaces. We then focuson the part of the context which specifies learning goals and their interrelations to task and domainmodels. Our purpose is to support learning needs analysis which is based on a comparison of tasksperformed in the past to those tasks to be tackled in the future. A first implementation in theAPOSDLE project is presented including the models generated for five real world applications andthe software prototype. We close with an outlook on future work.

Collaborative enterprise integrated modelling

Poster Session at the 16th International Conference on Knowledge Engineering and Knowledge Management Knowledge Patterns (EKAW 2008), 29th September-3rd October 2008 - Acitrezza, Catania, Italy, 2008

Konferenz
Enterprise modelling focuses on the construction of structured descriptions,the enterprise models, of sets of aspects relevant to the activity ofan enterprise. Nowadays, knowledge engineering provides powerful methodologiesand tools to support enterprise modeling in the production of formal models.These methods however present two main limitation: First, they are based ona waterfall process of transformation of informal knowledge into formal statements;Second, they tend to separate the modelling of the different aspects withoutproviding enough support to their final integration. In this paper we propose amore flexible framework that supports an agile collaboration between the actorsinvolved in the modelling activities, without sticking to a pre-defined protocolof interaction. In addition we propose an integrated meta-model that specifiesthe integration of single components of an articulated enterprise model as wellas their relations, and we report our experience of using the framework and themeta-model in the production of five enterprise models within the APOSDLEEU-project.

Modeling competencies for supporting work-integrated learning in knowledge work

Journal of knowledge management, Emerald Group Publishing Limited, 2008

Journal
Purpose – The purpose of this paper is to suggest a way to support work-integrated learning forknowledge work, which poses a great challenge for current research and practice.Design/methodology/approach – The authors first suggest a workplace learning context model, whichhas been derived by analyzing knowledge work and the knowledge sources used by knowledgeworkers. The authors then focus on the part of the context that specifies competencies by applying thecompetence performance approach, a formal framework developed in cognitive psychology. From theformal framework, a methodology is then derived of how to model competence and performance in theworkplace. The methodology is tested in a case study for the learning domain of requirementsengineering.Findings – The Workplace Learning Context Model specifies an integrative view on knowledge workers’work environment by connecting learning, work and knowledge spaces. The competence performanceapproach suggests that human competencies be formalized with a strong connection to workplaceperformance (i.e. the tasks performed by the knowledge worker). As a result, competency diagnosisand competency gap analysis can be embedded into the normal working tasks and learninginterventions can be offered accordingly. The results of the case study indicate that experts weregenerally in moderate to high agreement when assigning competencies to tasks.Research limitations/implications – The model needs to be evaluated with regard to the learningoutcomes in order to test whether the learning interventions offered benefit the user. Also, the validityand efficiency of competency diagnosis need to be compared to other standard practices incompetency management.Practical implications – Use of competence performance structures within organizational settings hasthe potential to more closely relate the diagnosis of competency needs to actual work tasks, and toembed it into work processes.Originality/value – The paper connects the latest research in cognitive psychology and in thebehavioural sciences with a formal approach that makes it appropriate for integration intotechnology-enhanced learning environments.Keywords Competences, Learning, Workplace learning, Knowledge managementPaper type Research paper

Recommending tags for pictures based on text, visual content and user context

Third International Conference on Internet and Web Applications and Services (ICIW), IEEE, 2008

Konferenz
Imagine you are member of an online social systemand want to upload a picture into the community pool. In currentsocial software systems, you can probably tag your photo, shareit or send it to a photo printing service and multiple other stuff.The system creates around you a space full of pictures, otherinteresting content (descriptions, comments) and full of users aswell. The one thing current systems do not do, is understandwhat your pictures are about.We present here a collection of functionalities that make a stepin that direction when put together to be consumed by a tagrecommendation system for pictures. We use the data richnessinherent in social online environments for recommending tags byanalysing different aspects of the same data (text, visual contentand user context). We also give an assessment of the quality ofthus recommended tags.

Modern businesses operate in a rapidly changing environment.Continuous learning is an essential ingredient in order to stay competitivein such environments. The APOSDLE system utilizes semanticweb technologies to create a generic system for supporting knowledgeworkers in different domains to learnwork. Since APOSDLE relies onthree interconnected semantic models to achieve this goal, the questionon how to efficiently create high-quality semantic models has become oneof the major research challenges. On the basis of two concrete examplesnamelydeployment of such a learning system at EADS, a large corporation,and deployment at ISN, a network of SMEs-we report in detail theissues a company has to face, when it wants to deploy a modern learningenvironment relying on semantic web technology.

Automating Knowledge Transfer and Creation in Knowledge Intensive Business Processes

Proceedings of the First Workshop on Business Process Management and Social Software BPMS2 08, September 1, 2008, Mailand, Italien, Springer, 2008

It is a well known fact that a wealth of knowledge lies in thehead of employees making them one of the most or even the most valuableasset of organisations. But often this knowledge is not documented andorganised in knowledge systems as required by the organisation, butinformally shared. Of course this is against the organisation’s aim forkeeping knowledge reusable as well as easily and permanently availableindependent of individual knowledge workers.In this contribution we suggest a solution which captures the collectiveknowledge to the benefit of the organisation and the knowledge worker.By automatically identifying activity patterns and aggregating them totasks as well as by assigning resources to these tasks, our proposed solutionfulfils the organisation’s need for documentation and structuring ofknowledge work. On the other hand it fulfils the the knowledge worker’sneed for relevant, currently needed knowledge, by automatically miningthe entire corporate knowledge base and providing relevant, contextdependent information based on his/her current task.

We present an analysis ofempirical data collected during and after the workshop.On the basis of this analysis, we conclude that the workshopwas an efficient way of generating ideas for futuresystem development. These ideas, on average, were usedat least as much as requirements from other sources inwriting use cases, and 18 months after the workshop wereseen to have a similar degree of influence on the projectto other requirements. We make some observations aboutthe use of more and less creative ideas, and about thetechniques used to generate them. We end with suggestionsfor further work.

Improving Search on the Semantic Desktop using Associative Retrieval Techniques

Proceedings of I-MEDIA 2007 and I-SEMANTICS 2007, Graz, Austria, September 5-7, 2007, 2007

Konferenz
While it is agreed that semantic enrichment of resources would lead tobetter search results, at present the low coverage of resources on the web with semanticinformation presents a major hurdle in realizing the vision of search on the SemanticWeb. To address this problem we investigate how to improve retrieval performancein a setting where resources are sparsely annotated with semantic information. Wesuggest employing techniques from associative information retrieval to find relevantmaterial, which was not originally annotated with the concepts used in a query. Wepresent an associative retrieval system for the Semantic Desktop and show how the useof associative retrieval increased retrieval performance.

Evaluating an Information Retrieval System for the Semantic Desktop using Standard Measures from Information Retrieval

Lernen - Wissen - Adaption LWA 2007, 2007

Konferenz
Evaluation of information retrieval systems is a critical aspect of information retrieval research. New retrieval paradigms, as retrieval in the Semantic Web, present an additional challenge for system evaluation as no off-the-shelf test corpora for evaluation exist. This paper describes the approach taken to evaluate an information retrieval system built for the Semantic Desktop and demonstrates how standard measures from information retrieval research are employed for evaluation.

APOSDLE: learn@work with semantic web technology

Proceedings of I-MEDIA 2007 and I-SEMANTICS 2007, Graz, Austria, September 5-7, 2007, 2007

Konferenz
The EU project APOSDLE focuses on work-integrated learning. Among the severalchallenges of the project, a crucial role is played by the system’s ability to start from the context ofthe immediate work of a user, establish her missing competencies and learning needs and suggeston-the-fly and appropriate learning stimuli. These learning stimuli are created from a variety ofresources (documents, videos, expert profiles, and so on) already stored in the workplace andmay be in the form of learning material or suggestions to contact experts and / or colleagues.To address this challenge requires the capability of building a system which is able find, choose,share, and combine a variety of knowledge, evolving content and resources in an automatic andeffective manner. The implementation of this capability requires technology which goes beyondtraditional query-answering and keyword based search engines, and Semantic Web technologywas chosen by the consortium as the most appropriate technology to make information search anddata integration more efficient. The aim of this paper is to give an overview of the broad spectrumof Semantic Web technologies that are needed for a complex application like APOSDLE, and thechallenges for the Semantic Web community that have appeared along the way.

Scruffy Technologies to Enable (Work-integrated) Learning

EC-TEL, 2007

Konferenz
The goal of the APOSDLE (Advanced Process-Oriented SelfDirectedLearning environment) project is to support work-integrated learningof knowledge workers. We argue that work-integrated learning requires extremeflexibility on a variety of aspects from supportive learning systems. Thisflexibility can not be achieved by typical (neat) eLearning systems. In this contributionwe present how a battery of scruffy technologies (e.g. combining semantics,associative networks and collective intelligence approaches) can beutilized to achieve this flexibility for user profile maintenance and contextbasedretrieval.

PROLEARN framework for process-oriented learning and knowledge work

2007

Given the importance of an organisation’s human capital to business success, aligning training and competencydevelopment with business needs is a key challenge. Many companies did initiate in the pastknowledge management activities or founded corporate universities as the organization intended to helpcompanies to face this challenge. In this deliverable, we talk about knowledge work and learning managementas a concept to “increase business performance” through a better short- and long-term learningapproach for people at management level. The aim is to provide a guideline for corporate users based onour and others' experiences of implementing solutions for knowledge work and learning. This is connectedto many forms and methods of learning: formal learning processes, informal learning, team learning,collaboration, social networking, community building etc. In many companies, managers think thatknowledge work can be supported solely by offering courses and enabling to access content on demand.In this deliverable this aspect (ACQUIRING knowledge) will not be in focus as it is more the job of atraining department to manage courses and catalogues. Instead we focus on APPLYING knowledge. Theconcept of knowledge work management comes into place, when companies see the ability of their employeesto APPLY their education and knowledge as a strategic instrument to create competitiveness andlook for tools to provide learning and knowledge at workplace on demand and fitting to the individualneeds. And this objective is very actual as the globalization creates pressure on companies and theknowledge and experience of the employees gets the most important differentiator to competitors – leadingto better innovation, faster processes, higher productivity and lower costs. In this deliverable, anoverall approach and guideline for companies will be provided on how to implement knowledge workmanagement and provide learning according to the needs in business and resulting from business processes.

The OntologyMapper plug-in: Supporting Semantic Annotation of Text-Documents by Classification

Semantic Systems From Vision to Applications - Proceedings of the SEMANTICS 2006, Vienna, Austria, November 28-30, 2006, Österreichische Computer Gesellschaft, Wien, 2006

Konferenz
In this contribution we present a tool for annotating documents, which are used for workintegratedlearning, with concepts from an ontology. To allow for annotating directly whilecreating or editing an ontology, the tool was realized as a plug-in for the ontology editor Protégé.Annotating documents with semantic metadata is a laborious task, most of the time knowledgerepresentations are created independently from the resources that should be annotated andadditionally in most work environments a high number of documents exist. To increase theefficiency of the person annotating, in our tool the process of assigning concepts to text-documentsis supported by automatic text-classification.

Synergizing Standard and Ad-Hoc Processes

Lecture Notes in Computer Science LNAI 4333, International Conference on Practical Aspects of Knowledge Management, Springer Berlin, Berlin Heidelberg, 2006

Konferenz
In a knowledge-intensive business environment, knowledgeworkers perform their tasks in highly creative ways. This essential freedomrequired by knowledge workers often conflicts with their organization’sneed for standardization, control, and transparency. Within thiscontext, the research project DYONIPOS aims to mitigate this contradictionby supporting the process engineer with insights into the processexecuter’s working behavior. These insights constitute the basis for balancedprocess modeling. DYONIPOS provides a process engineer supportenvironment with advanced process modeling services, such as processvisualization, standard process validation, and ad-hoc process analysisand optimization services.

A network model approach to document retrieval taking into account domain knowledge

In Martin Schaaf and Klaus-Dieter Althoff (Ed.), Proceedings LWA 2006 - Lernen - Wissensentdeckung - Adaptivität, Hildesheim, Germany, October 9-11, 2006, Universität Hildesheim, Hildesheim, 2006

Konferenz
We preset a network model for context-based retrievalallowing for integrating domain knowledgeinto document retrieval. Based on thepremise that the results provided by a networkmodel employing spreading activation are equivalentto the results of a vector space model, wecreate a network representation of a documentcollection for retrieval. We extended this well exploredapproach by blending it with techniquesfrom knowledge representation. This leaves uswith a network model for finding similarities in adocument collection by content-based as well asknowledge-based similarities.

Challenges for learning in knowledge work are being discussed.These include the challenge to better support self-directed learning whileaddressing the organizational goals and constraints at the same time, andproviding guidance for learning. The use of competencies is introduced as away to deal with these challenges. Specifically, the competence performanceapproach offers ways to better leverage organizational context and to supportinformal learning interventions. A case study illustrates the application of thecompetence performance approach for the learning domain of requirementsengineering. We close with conclusions and an outlook on future work.

A Context-Model for Supporting Work-Integrated Learning

European Conference on Technology Enhanced Learning, Innovative Approaches for Learning and Knowledge Sharing , Springer, Berlin, 2006

Konferenz
This contribution introduces the so-called Workplace Learning Contextas essential conceptualisation supporting self-directed learning experiencesdirectly at the workplace. The Workplace Learning Context is to be analysedand exploited for retrieving ‘learning’ material that best-possibly matches witha knowledge worker’s current learning needs. In doing so, several different‘flavours’ of work-integrated learning can be realised including task learning,competency-gap based support and domain-related support. The WorkplaceLearning Context Model, which is also outlined in this contribution, forms thetechnical representation of the Workplace Learning Context.

Competency Management using the Competence Performance Approach: Modeling, Assessment, Validation and Use

in: Sicilia, M.A. (Ed.), Competencies in Organizational E-Learning: Concepts and Tools, Information Science Publishing, Hershey, PA, 2006

Buch
This chapter introduces a new approach in organizational competency management, which is based on Korossy's competence performance approach and which rests on the central idea of connecting competencies to actual job performance. Such an approach has several important benefits when compared to more traditional approaches. First, it brings competency modeling and assessment more closely to the actual work processes and tasks. Second, it makes possible validation of the models and the assessment within the modeling and assessment porcedure. Finally, it is better able to cope with more dynamic and knowledge-based settings. Three case studies in engineering, human resource management and research and development illustrate how the approach is introduced, evaluated and applied. The purpose of the chapter is to inform researchers in e-learning and knowledge management of how competencies can be used to support work-integrated assessment and learning.

Ontology Coverage Check: Support for Evaluation in Ontology Engineering

Proceedings of FOMI 2006 - 2nd Workshop on Formal Ontologies Meet Industry, Trento, Italy, December 14-15, 2006, 2006

Konferenz
Support for the process of ontology engineering is needed in order to reduce theeffort still necessary to build an ontology. Some can be given by facilitated evaluationof the ontology under development. To that purpose we present an automated methodthat supports data driven ontology evaluation by checking to what extent the conceptsand axioms of the ontology under evaluation are covered by a given set of individuals(data).We applied the here presented ontology coverage check (OCC) to various ontologiesand will report on the results. The results highlight not only the potential of OCCbut also some characteristics of ontologies currently available to the public.

Journal of universal knowledge management, 2006

Journal
Requirements engineering has grown into a focus topic for most software-dependentcompanies. Both outsourcing and in-house development call for effective elicitation ofrequirements, and for rich communication between customers and software developers.Organizational learning is, therefore, a natural complement when we discuss requirementsengineering practice and its improvement. Through organizational learning, processes and toolsare systematically improved, reflection and explicit learning becomes part of the companyculture. Many companies are still struggling to reach this goal.The LSO+RE workshop has provided a forum for discussing the intersection of requirementsengineering and learning software organizations in depth. This article introduces the topic andthe articles from the LSO+RE workshop that have been selected for this special issue ofJ.UKM.

A Knowledge Infrastructure Hierarchy Model for Call-Centre Processes

Journal of Universal Computer Science, 2005

Journal
This paper explores a process view of call-centres and the knowledge infrastructuresthat support these processes. As call-centres grow and become more complex in their functionand organisation so do the knowledge infrastructures required to support their size andcomplexity. This study suggests a knowledge-based hierarchy of ‘advice-type’ call-centres anddiscusses associated knowledge management strategies for different sized centres. It introducesa Knowledge Infrastructure Hierarchy model, with which it is possible to analyze and classifycall-centre knowledge infrastructures. The model also demonstrates different types ofinterventions supporting knowledge management in call-centres. Finally the paper discusses thepossibilities of applying traditional maturity model approaches in this context.

Integrating Business Processes and Knowledge Infrastructures

Journal of Universal Computer Science, 2005

Journal
The integration of available knowledge management technologies, concepts andmethods into organizational business processes is a pressing and challenging researchissue today. Researches and practitioners in the areas of process and knowledgemanagement alike seek for solutions that aid the flexible alignment of knowledgemanagement efforts to an organization’s most value generating activities. Theadvantages inherent in such efforts are manifold: The execution of business processesis supported from a knowledge perspective, the economic benefit of knowledgemanagement can be illustrated more easily and knowledge management activitiesbecome “alive” because of the integration in organizational business processes -which in turn thrives business performance.The special issue “Integrating Business Processes and KnowledgeInfrastructures” makes more detailed versions of the contributions to BPOKI’04available. BPOKI’04 is a special track series on Business Process OrientedKnowledge Infrastructures that took place the first time during I-Know’04, the 4thInternational Conference on Knowledge Management (http://www.iknow.at/BPOKI).The purpose of this special issue is to provide readers with an overview of up-todateresearch on the intersection between business process and knowledgemanagement. Contributions of this special issue consider both, organizational as wellas technological aspects of this topic, and fall in one of the following four categories:1) Business Process Modelling 2) Business Process Learning 3) Business ProcessSupport and 4) Business Process Execution.

Beyond flexible Information Systems: Why Business Agility Matters

Proceedings of the CAiSE 05 Workshop BPMDS 05 on Business Process Modeling, Development, and Support: Business Processes and Support Systems: Design for Flexibility, Castro, J., Teniente, E., Porto, Portugal, 2005

Konferenz
Today, organizations need to act and perform in increasinglydynamic environments. Current research on flexibility of information systemsaims to provide answers to this fact. Yet, we show that the concept of flexibilityalone does not suffice to address this challenge. Therefore, this paper introducesthe notion of business agility that extends the concept of flexibility anddescribes further necessary areas of research. We identify a perception gapwhich argues that current concepts of flexibility do not actively search forchallenges or opportunities of change in the environment. Instead, flexibility iscommonly perceived to be a rather passive characteristic. Based on thisobservation, our contribution introduces an exemplary instrument that addressesthe identified perception gap and aids organizations in achieving higher degreesof business agility and thus, increases the capability of organizations to act andperform under uncertain conditions. The overall contribution of this paper is anextended perspective on the concept of flexibility, the identification of furthernecessary areas of research and the introduction of an instrument that addressesaspects of the identified issues.

Improving Service Innovation through Structured Process-oriented Knowledge Infrastructure Design

Proceedings of the I-KNOW`05, 5th International Conference on Knowledge Management, Springer, Graz, Austria, 2005

Konferenz
Formalised service innovation is a central tenet of enterprise systems lifecyclephases. Event driven process models extended with knowledge objects are found to be notuseful in early lifecycle phases. When an upgrade is required, a map of the knowledgeinfrastructure is needed to better design further service innovation because functional maps nolonger adequately describe the context adequately. By looking at formal changes to businessprocesses as service innovations, and recognising the knowledge infrastructure inherent inservices generally, changes driven through technology such as ES can be better understoodwith the application of frameworks such as B-KIDE.

Supporting Competency Development in Informal Workplace Learning

Lecture Notes in Artificial Intelligence, Althoff, K.-D., Dengel, A., Bergmann, R., Nick, M., Roth-Berghofer, T., Springer, Heidelberg, 2005

Konferenz
This paper seeks to suggest ways to support informal, self-directed, work-integrated learning within organizations. We focus on a special type of learning in organizations, namely on competency development, that is a purposeful development of employee capabilities to perform well in a large array of situations. As competency development is inherently a self-directed development activity, we seek to support these activities primarily in an informal learning context. AD-HOC environments which allow employees context specific access to documents in a knowledge repository have been suggested to support learning in the workplace. In this paper, we suggest to use the competence performance framework as a means to enhance the capabilities of AD HOC environments to support competency development. The framework formalizes the tasks employees are working in and the competencies needed to perform the tasks. Relating tasks and competencies results in a competence performance structure, which structures both tasks and competencies in terms of learning prerequisites. We conclude with two scenarios that make use of methods established in informal learning research. The scenarios show how competence performance structures enhance feedback mechanisms in a coaching process between supervisor and employee and provide assistance for self directed learning from a knowledge repository.

AD-HOC - Work-integrated Technology-supported Teaching and Learning

Proceedings of the 5th International Conference on Organizational Knowledge, Learning, and Capabilities, Innsbruck, 2004

Konferenz
Carrying out today’s knowledge work without information and communicationtechnology (ICT) is unimaginable. ICT makes it possible to process and exchangeinformation quickly and efficiently. However, accomplishing tasks with ICT isoften tedious: Colleagues have to be asked, how best to proceed. Necessaryresources have to be searched for in the intranet and internet. And one has toget familiar with applying the various systems and tools. This way, solving asimple task can become a time consuming process for inexperienced employeesand also for those who are asked for their expertise.Therefore, at the Know-Center Graz, Austria , the AD-HOC methodology hasbeen developed to support knowledge workers in task-oriented learning andteaching situations. This methodology is used to analyse the work processes, toidentify the needed resources, tools, and systems, and finally to design an ADHOCEnvironment. In this environment, systems and tools are arranged forspecific work processes. Users are then guided at their work tasks and areprovided with the necessary resources instantly.This article presents the AD-HOC methodology. It analyses the obstacles thathamper efficient knowledge work and how AD-HOC overcomes them. Finally, thesupport of users at their specific work tasks by deployed AD-HOC Environmentsis shown in two field studies.

Integration von Prozess- und Wissensmanagement-orientierten Designstrategien zur Erstellung benutzerfreundlicher Unternehmensportale

Wissensmanagement 2003 - 2. Konferenz Professionelles Wissensmanagement, Luzern/Schweiz, 2.-4.4.2003, Reimer, U., Abecker, A., Staab, S., Stumme, G., Köllen Druck Verlag GmbH, Luzern, Schweiz, 2003

Konferenz
Personalisierbare Portale als Fenster zu Unternehmensgedachtnissen finden ¨in der Praxis immer haufiger Anwendung. Bei dem Design dieser Portale stellt sich die ¨Frage nach der Strukturierung der Informationen: auf der einen Seite soll der tagliche ¨Arbeitsprozess unterstutzt werden, auf der anderen Seite sollen aber auch Informa- ¨tionen zuganglich gemacht werden, die den Prozess in einen gr ¨ oßeren Kontext set- ¨zen. Unsere Erfahrungen bei der Portalentwicklungen haben gezeigt, dass zwei unterschiedlicheStrategien Anwendung finden: Prozessfokus und Wissensfokus. Die Wahlder individuellen Strategie hangt einerseits von den Zielen ab, die das Portal erf ¨ ullen ¨soll. Andererseits hangen sie aber auch von der Ausgangssituation im anwendenden ¨Unternehmen ab. Dieser Beitrag stellt die beiden Designstrategien vor und identifiziertRahmenbedingungen, die bei der Wahl der Stategie helfen konnen.

Knowledge Management within Digital Libraries by means of Personalization

Journal of Universal Computer Science (J.UCS), Proceedings of I-KNOW02, 2nd International Conference on Knowledge Management, July 11-12, 2002, Graz, Austria, 2002

Konferenz
This paper presents research results obtained from the project Personal AdaptableDigital Library Environment (PADDLE). The main focus of the DFG funded research projectis to apply concepts of knowledge management to digital libraries by introducingpersonalization techniques. The idea is to enable the specific needs, experiences, skills andtasks of a knowledge worker using a digital library could be taken into account. Metadata is thekey issue for doing this. Therefore the PADDLE system architecture describes a metadatamanager, which allows the association of metadata with the knowledge objects stored indistributed information resources. Based on this architecture several personalization conceptslike workspaces and profiles are introduced. Finally, a geographic information portal isdescribed that realizes a new way of seeking and accessing geodata related knowledge objectswithin a digital library.

KMap: Providing Orientation for Practitioners when Introducing Knowledge Management

Proceedings of the 4th International Conference on Practical Aspects of Knowledge Management (PAKM 2002), Springer, Vienna Austria, 2002

Konferenz
One of the first question each knowledge management project facesis: Which concrete activities are referred to under the name of knowledgemanagement and how do they relate to each other? To help answer this questionand to provide guidance when introducing knowledge management we havedeveloped KMap. KMap is an environment which supports a practitioner in theinteractive exploration of a map of knowledge management activities. Theinteraction helps trigger interesting questions crucial to the exploration of thesolution space and makes hidden argumentation lines visible. KMap is not anew theory of knowledge management but a pragmatic “object to think with”and is currently in use in two case studies.

Aufgaben-Orientiertes Kooperatives Lernen

Informatik bewegt: Informatik 2002 - 32. Jahrestagung der Gesellschaft für Informatik e.v. (GI), Gesellschaft für Informatik e.v. (GI), Dortmund, Germany, 2002

Konferenz
Wir betrachten kooperative Lern- und Lehrsituationen im Kontext dertäglichen Arbeitsprozesse aus der Perspektive des Wissensmanagements. In einerCase Study bei DaimlerChrysler wurden Szenarien entwickelt, in denen Wissen inGruppen erarbeitet und weitergegeben wird, um konkrete Arbeitsaufgaben unterZeitdruck erfüllen zu können. Zur Zeit entwickeln wir im Kontext eines WissensmanagementsystemsMethoden und technische Hilfsmittel zur Unterstützung dieseraufgaben-orientierten kooperativen Lern- und Lehrprozesse.

ECTEL meets ECSCW: Computer-Support for Integrated Working and Learning

ECSCW 2013 Adjunct Proceedings

Konferenz
With this workshop, we intend to bring together the European communities of technology-enhanced learning, which typically meets at the ECTEL, and of computersupported cooperative work, which typically meets at the ECSCW. While the ECTEL community has traditionally focused on technology support for learning, be it in formal learning environments like schools, universities, etc. or in informal learning environments like workplaces, the ECSCW community has traditionally investigated how computers can and do mediate and influence collaborative work, in settings as diverse as the typical “gainful employment” situations, project work within university courses, volunteer settings in NGOs etc. Despite overlapping areas of concerns, the two communities are also exploiting different theories and methodological approaches. Within this workshop, we discuss issues that are relevant for both communities, and have the potential to contribute to a more lively communication between both communities.

APOSDLE-learn@work: Firsthand Experiences and Lessons Learned

Work-Integrated Learning in Engineering, Built Environment and Technology: Diversity of Practice in Practice, IGI Global

Buch
This chapter presents a domain-independent computational environment which supports work-integrated learning at the professional workplace. The Advanced Process-Oriented Self-Directed Learning Environment (APOSDLE) provides learning support during the execution of work tasks (instead of beforehand), within the work environment of the user (instead of within a separate learning system), and repurposes content which was not originally intended for learning (instead of relying on the expensive manual creation of learning material). Since this definition of work-integrated learning might differ from other definitions employed within this book, a short summary of the theoretical background is provided. Along the example of the company Innovation Service Network (ISN), a network of SME’s, a rich and practical description of the deployment and usage of APOSDLE is given. The chapter provides the reader with firsthand experiences and discusses efforts and lessons learned, backed up with experiences gained in two other application settings, namely EADS in France and a Chamber of Commerce and industry in Germany.
