Tagr: Unterstützung in kollaborativen Tagging-Umgebungen durch semantische und assoziative Netzwerke

GMW Expert Workshop" Social Tagging in der Wissensorganisation–Perspektiven und Potenziale", Tübingen, 2008

Stellen Sie sich vor, Sie laden ein Bild auf Flickr hoch und bekommen automatisch Vorschläge für Tags, sowie Beispiele wie ähnliche Bilder beschlagwortet worden sind. Wir stellen den Forschungsprototypen tagr vor, der auf Basis von vorhandenen Tags Information über die Benutzerin sowie eine Analyse des Bildes neue Tags für ein Bild vorschlägt. Wir verstehen kollaboratives Tagging als einen Prozess der verteilten Kognition, den wir mit entsprechenden Diensten unterstützen wollen. Wir gehen in diesem Artikel genauer auf den Termähnlichkeitsservice ein, der sich ein semantisches Netzwerk (WordNet) und ein assoziatives Netzwerk (Kookkurrenz der verwendeten Tags) zu Nutze macht. Wir diskutieren die Evaluierung des Prototypen und schließen mit einem Ausblick auf unsere weiteren Arbeiten.

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.

Towards a Framework for Social Web Platforms: The Neurovation Case

Proceedings of the Third International Conference on Internet and Web Applications and Services (ICIW 2008), IEEE Computer Society Press, 2008

Konferenz
Social web platforms have become very popular in the so-called Web 2.0, and there is no end in sight. However, very few systematic models for the constitution of such sociotechnical infrastructures exist in the scientific literature. We therefore present a generic framework for building social web platforms based on the creation of value for individuals, communities and social networks. We applied this framework in the Neurovation project, aiming to establish a platform for creative knowledge workers. This paper describes work in progress and the lessons we have learned so far.

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.

Deploying semantic web technologies for work integrated learning in industry. A comparison: SME vs. large sized company

Proceedings of the ISWC 2008, 7th International Semantic Web Conference, Karlsruhe, Germany, Oct 26-30, 2008 , Springer, 2008

Konferenz
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.

Collaborative Knowledge Engineering via Semantic MediaWiki

Proceedings of the I-Semantics 2008, Graz, Austria, Sep. 3-5 2008, 2008

Konferenz
Formal modelling is a challenging and expensive task, especially for people not familiarwith design techniques and formal languages. In this paper we present the modelling experiencewithin the APOSDLE EU-project, and we describe the methodology we have developedto support an integrated modelling process of the ontologies and workflows inside APOSDLE.Our approach is based on two main pillars: (i) the usage of Semantic MediaWiki (SMW) forthe collaborative development of informal models to be created, and (ii) a tight, and as much aspossible automatic, integration of the SMW with tools for formal modelling, in order to reuse theinformal models for formal models creation.

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.
