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.

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.

Information Retrieval on the Semantic Web - Does it exist?

Proceedings of Lernen-Wissen-Adaption, Halle/Saale, Germany, September 24-26, 2007, 2007

Konferenz
Plenty of contemporary attempts to search existthat are associated with the area of Semantic Web.But which of them qualify as information retrievalfor the Semantic Web? Do such approaches exist?To answer these questions we take a look at thenature of the Semantic Web and Semantic Desktopand at definitions for information and data retrieval.We survey current approaches referred toby their authors as information retrieval for the SemanticWeb or that use Semantic Web technologyfor search.

Two Protégé plug-ins for supporting document-based ontology engineering and ontological annotation at document-level

10th International Protégé Conference, Budapest, Hungary, July 15-18, 2007, Budapest, 2007

We present two plug-ins for Prot´eg´e OWL. The first, Discovery Tab,supports document-based ontology engineering with relevant term extraction,clustering and related functionality. The second, Annotation Tab,provides a facility to annotate documents manually and automatically(based on a training set).

Rapid Knowledge Work Visualization for Organizations

Journal of Knowledge Management, Emerald Group Publishing Limited, 2007

Journal
Purpose: The purpose of this contribution is to motivate a new, rapid approachto modeling knowledge work in organizational settings and to introducea software tool that demonstrates the viability of the envisioned concept.Approach: Based on existing modeling structures, the KnowFlowr Toolsetthat aids knowledge analysts in rapidly conducting interviews and in conductingmulti-perspective analysis of organizational knowledge work is introduced.Findings: It is demonstrated how rapid knowledge work visualization can beconducted largely without human modelers by developing an interview structurethat allows for self-service interviews. Two application scenarios illustrate thepressing need for and the potentials of rapid knowledge work visualizations inorganizational settings.Research Implications: The efforts necessary for traditional modeling approachesin the area of knowledge management are often prohibitive. Thiscontribution argues that future research needs to take economical constraintsof organizational settings into account in order to be able to realize the fullpotential of knowledge work management.Practical Implications: This work picks up a problem identified in practiceand proposes the novel concept of rapid knowledge work visualization for makingknowledge work modeling in organizations more feasible.Value: This work develops a vision of rapid knowledge work visualization andintroduces a tool-supported approach that addresses some of the identified challenges.

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.

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.

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.
