ISWC Conferencepp 467-482LNCSEvaluating long-term use of the Gnowsis Semantic Desktop for PIM5318200810 2008 dfki from:leobard imported iswc iswc2008 lang:en nepomuk semanticdesktop semanticweb semdesk wp2 The Semantic Desktop is a means to support users in Personal Information Management (PIM). Using the open source software prototype Gnowsis, we evaluated the approach in a two month case study in 2006 with eight participants. Two participants continued using the prototype and were interviewed after two years in 2008 to show their long-term usage patterns. This allows us to analyse how the system was used for PIM. Contextual interviews gave insights on behaviour, while questionnaires and event logging did not. We discovered that in the personal environment, simple has-Part and is-related relations are sufficient for users to file and re-find information, and that the personal semantic wiki was used creatively to note information.Wed Aug 13 11:22:16 CEST 200810th International Conference on Enterprise Information Systems, ICEIS 2008JuneComparing People in the Enterprise2008from:demartini l3s nepomuk wp5 Enterprise Search Systems are requested to provide more and more functionalities for supporting decision at the management level. An important aspect to consider is the human power and the knowledge which is available. For this reason, in this paper, after extracting a list of requirements out of a specific scenario, and presenting the previous work, we describe an improved approach to compare experts in order to retrieve and present to the user the most appropriate candidates for a given projectWed Aug 13 11:22:16 CEST 2008FEWS 2007: Finding Experts on the Web with Semantics Workshop at ISWC 2007 + ASWC 2007NovemberFinding Experts Using Wikipedia2007from:demartini l3s nepomuk wp5 When we want to find experts on the Web we might want to search where the knowledge is created by the users. One of such knowledge repository is Wikipedia. People expertises are described in Wikipedia pages and also the Wikipedia users can be considered experts on the topics they produce content on. In this paper we propose algorithms to find experts in Wikipedia. The two different approaches are finding experts in the Wikipedia content or among the Wikipedia users. We also use semantics from WordNet and Yago in order to disambiguate expertise topics and to improve the retrieval effectiveness. In the end, we show how our methodology can be implemented in a system in order to improve the expert retrieval effectiveness.Wed Aug 13 11:22:16 CEST 2008PIKM 2007: 1st ACM International Workshop for Ph.D. Students in Information and Knowledge ManagementNovemberLeveraging Semantic Technologies for Enterprise Search2007from:demartini l3s nepomuk wp5 Enterprise search is very different from Web search (for example in the link structure or in the user’s needs and goal) and some steps have been already done to exploit these differences in order to improve the effectiveness of enterprise search. In this paper we present the state of the art of the enterprise search field with some open issues. We also present a research plan that aims at using Information Retrieval, Semantic Web, and User Modelling techniques to cope with these issues improving the current state of enterprise search.Wed Aug 13 11:22:16 CEST 2008Personal Information Management Workshop at CHI 2008AprilEvaluating Personal Information Management Using an Activity Logs Enriched Desktop Dataset2008from:demartini l3s nepomuk wp5 The effective evaluation of Personal Information Management is a crucial problem for the research community. While evaluation methodologies for retrieval on the Web and in digital libraries are well-developed, the experiments with the advanced desktop tools are neither repeatable nor comparable. As privacy concerns do not allow to copy and distribute personal data outside the research lab, we suggest to overcome this problem by creation of desktop datasets within different research groups using a single methodology and a common set of tools. A dataset can include not only a static snapshot of the desktop documents, but also the logs of user activity on the desktop within several last months. We present the structure of the required dataset, a set of implemented tools and a sample dataset collected within the L3S Research Center.Wed Jun 18 21:26:52 CEST 200803Leo Sauermann was invited to present slides about NEPOMUK at the Studecki Festiwal Informatyczny, an bigger event organized by polish students. http://www.sfi.org.pl/Presentation of NEPOMUK at Krakow Student Festival200803 2008 dfki from:leobard lang:en nepomuk wp2 Wed Jun 18 21:26:52 CEST 200804Presentation of NEPOMUK and Case Studies at Oil Industry Norway Semantic Web Days200804 2008 dfki from:leobard nepomuk wp2 Presentation of case studies of successfull Semantic Web use, NEPOMUK is one of them.

Es werden Beispiele vorgestellt sowie Startpunkte für die Suche nach Ontologien gegeben, die sich für EAI via SOA und Web anbieten. Im Anschluss werden Tools gezeigt, die die einschlägigen Standards (RDF, OWL, SPARQL) auf Java-Ebene transportieren.Thu Feb 14 13:50:10 CET 2008February2008-1The Sesame Lucene Sail: RDF Queries with Full-text SearchTechnical Report200802 2008 aduna dfki from:leobard imported l3s lang:en nepomuk wp2 With the growth of the Semantic Web, the requirements on storing and querying RDF has become more sophisticated. When a larger amount of data has to be managed, queries in structured query languages, such as SPARQL, are not always powerful enough. Use of additional keywords for querying can further reduce the result set towards the actual relevant answers, however, SPARQL only provides complete string matching or filtering based on regular expressions, which is a very slow operation. In contrast, state of the art Information Retrieval (IR) techniques provide sophisticated features such as keyword search, lemmatisation, stemming and ranking. In this paper we present a combination of structured RDF queries and full-text search. It is implemented as an extension of an established RDF store (Sesame) with IR capabilities using the text search library Lucene, without requiring modifications to existing RDF query languages.

Wir haben genug Platz, um all unsere E-Mails, MP3s, Photos, Videos und Dokumente am Desktop zu speichern. Das Problem ist, diese Information zu verwalten. Dateisysteme bieten nur starre Hierarchien an. Tim Berners-Lee und das W3C haben bereits weiter gedacht: Menschen denken in Konzepten, das Semantic Web bietet mit RDF und Ontologien einen auf HTTP, URIs und HTML aufbauenden Standard zur Annotation und Suche. Der Semantic Desktop bringt Betriebssysteme und Anwendungen damit weg von den Dateien, auf die Stufe der Gedanken.
