This model paves the way for semantic annotation of implicit, well-defined workflows, thus making them explicit and exposing the missing information in a machine processable way. Grounding this work within the Social Semantic Desktop [1] via appropriate ontologies means that this information can be exploited for the benefit of the user. This will have a direct impact on their personal information management - given email is not just a major channel of data exchange between desktops, but it also serves as a virtual working environment where people collaborate. Thus the presented workflow model will have a concrete manifestation in the creation, organization and exchange of semantic desktop data.http://www.bibsonomy.org/bibtex/2e89c1407d23363623b309b221e2ca1e9/eswc2008eswc20082008-05-28T14:50:00+02:00document semantic search spreading desktop activation retrieval <span style="color:#555555;">Kinga <a href="http://www.bibsonomy.org/author/Schumacher">Schumacher</a> and Michael <a href="http://www.bibsonomy.org/author/Sintek">Sintek</a> and Leo <a href="http://www.bibsonomy.org/author/Sauermann">Sauermann</a> </span><em>Proceedings of the 5th European Semantic Web Conference, </em><em>Berlin, Heidelberg, </em><em>Springer Verlag, </em><em>June 2008. </em>Wed May 28 14:50:00 CEST 2008Berlin, HeidelbergProceedings of the 5th European Semantic Web ConferenceJuneLNCSCombining Meta Data and Document Search with Spreading Activation for Semantic Desktop Search2008document semantic search spreading desktop activation retrieval The Semantic Desktop is a means to support users in Personal Information Management (PIM). It provides an excellent test bed for Semantic Web technology: resources (e. g., persons, projects, messages, documents) are distributed amongst multiple systems, ontologies are used to link and annotate them. Finding information is a core element in PIM. For the end user, the search interface has to be intuitive to use, natural language queries provide a simple mean to express requests. State of the art semantic search engines focus on metadata search or on semantic document retrieval. We combine both approaches to search the Semantic Desktop exploiting all available information, where we build on semantic teleporting and spreading activation. This combination is able to answer queries with instances, subgraphs of the knowledge base, and with relevant documents. We evaluated our approach on ESWC 2007 data in comparison with Google site search.http://www.bibsonomy.org/bibtex/26e70f101963dbb1cc14244a34183031f/eswc2008eswc20082008-05-28T14:49:58+02:00exploratory interfaces management visualization ontology social personal semantic desktop user information pimo applications-1 <span style="color:#555555;">VinhTuan <a href="http://www.bibsonomy.org/author/Thai">Thai</a> and Siegfried <a href="http://www.bibsonomy.org/author/Handschuh">Handschuh</a> and Stefan <a href="http://www.bibsonomy.org/author/Decker">Decker</a> </span><em>Proceedings of the 5th European Semantic Web Conference, </em><em>Berlin, Heidelberg, </em><em>Springer Verlag, </em><em>June 2008. </em>Wed May 28 14:49:58 CEST 2008Berlin, HeidelbergProceedings of the 5th European Semantic Web ConferenceJuneLNCSIVEA: An Information Visualization Tool for Personalized Exploratory Document Collection Analysis2008exploratory interfaces management visualization ontology social personal semantic desktop user information pimo applications-1 Knowledge work in many fields requires examining several aspects of a collection of documents to attain meaningful understanding that is not explicitly available. Despite recent advances in document corpus visualization research, there is still a lack of principled approaches which enable the users to personalize the exploratory analysis process. In this paper, we present IVEA (Information Visualization for Exploratory Document Collection Analysis), an innovative visualization tool which employs the PIMO (Personal Information Model) ontology to provide the knowledge workers with an interactive interface allowing them to browse for information in a personalized manner. Not only does the tool allow the users to integrate their personal knowledge into the exploration and analysis of a document collection, it also enables them to incrementally enrich their PIMO ontologies with new entities matching their evolving interests in the process, benefiting the users not only in their future experience with IVEA but also with other PIMO-based applications. The usability of the tool was preliminarily evaluated and the results were sufficiently encouraging to make it worthwhile to conduct a larger-scale usability study.
