Topic-centric information including experts is served on OntoFrame, which is a Semantic Web-based academic research information service supporting R&D activities. URI scheme-based OntoFrame provides three entity pages: topic, person, and event. ‘Persons by Topic’ in topic page lists up topic-centric identified experts. SPARQL query is used to re-trieve them from RDF triple store through backward chaining. We gathered CiteSeer open access metadata and full text documents with the amount of about 110,000 papers. Using about 160,000 abundant topics, OntoFrame now serves topic-centric identified experts and relevant information acquired by full text analysis.http://www.bibsonomy.org/bibtex/27f7ac73677841b4580461d408e83495a/claudia.wagnerclaudia.wagner2009-12-13T09:57:16+01:00folksonomy semantic tagging wordnet <span class="authorEditorList"><a href="/author/Laniado">David Laniado</a>, <a href="/author/Eynard">Davide Eynard</a>, and <a href="/author/Colombetti">Marco Colombetti</a> </span><em>Semantic Web Application and Perspectives - Fourth Italian Semantic Web Workshop, </em><em>page 192--201. </em>(<em>December 2007</em>)Sun Dec 13 09:57:16 CET 2009Semantic Web Application and Perspectives - Fourth Italian Semantic Web WorkshopDec192--201Using WordNet to turn a folksonomy into a hierarchy of concepts2007folksonomy semantic tagging wordnet http://www.bibsonomy.org/bibtex/2161371ad4b336e083cde3a13bf8a3085/claudia.wagnerclaudia.wagner2009-05-07T13:10:35+02:00community <span class="authorEditorList"><a href="/author/Koch">Michael Koch</a> </span><em>Technische Universität München, Fakulät für Informatik, </em>(<em>2003</em>)Thu May 07 13:10:35 CEST 2009Community-Unterstützungssysteme - Architektur und Interoperabilität (Habilitation).2003community http://www.bibsonomy.org/bibtex/26d89aa118b4c4b39abc73b06b0e99123/claudia.wagnerclaudia.wagner2009-04-10T23:58:31+02:00imported <span class="authorEditorList"><a href="/author/Handschuh">Siegfried Handschuh</a> </span><em>Semantic Web Services</em> (<em>2007</em>)Fri Apr 10 23:58:31 CEST 2009Semantic Web Services135--155Semantic Annotation of Resources in the Semantic Web2007imported In this chapter, we give a brief introduction into the main idea of the Semantic Web, namely making better use and enabling more intelligent applications for Web-accessible information by accompanying them with machine-understandable, semantic metadata; we sketch the major methodological framework behind, consisting of two intertwined, orthogonal processes, the knowledgeprocess and the knowledge meta process–the latter is concerned with ontology engineering, the former uses ontologies for ontology-basedmeta-data assignment to Web resources, i.e. for semantic annotation. The major part of the chapter is devoted to the ideaof semantic annotation, requirements and functionalities of annotation tools, an example implementation and an overview ofthe state of research and practice in semantic annotation.SpringerLink - Buchkapitelhttp://www.bibsonomy.org/bibtex/231e501e9bfe4b3d78ec78009dcd98f3b/claudia.wagnerclaudia.wagner2009-03-21T13:37:34+01:00URI xpointer <span class="authorEditorList"><a href="/author/Clark">Kendall Clark</a>, <a href="/author/Parsia">Bijan Parsia</a>, <a href="/author/Thompson">Bryan Thompson</a>, and <a href="/author/Bebee">Bradley Bebee</a> </span><em>The Semantic Web – ISWC 2004</em> (<em>2004</em>)Sat Mar 21 13:37:34 CET 2009The Semantic Web – ISWC 2004564--575A Semantic Web Resource Protocol: XPointer and HTTP2004URI xpointer Semantic Web resources — that is, knowledge representation formalisms existing in a distributed hypermedia system — require different addressing and processing models and capacities than the typical kinds of World Wide Web resources. We describe an approach to building a Semantic Web resource protocol — a scalable, extensible logical addressing scheme and transport protocol — by using and extending existing specifications and technologies. We introduce XPointer and some infrequently used, but useful features of HTTP/1.1, in order to support addressing and server side processing of resource and subresource operations. We consider applications of the XPointer Framework for use in the Semantic Web, particularly for RDF and OWL resources and subresources. We describe two initial implementations: filtering of RSS resources by date and item range; RDF subresource selection using RDQL. Finally, we describe possible application to the problem of OWL imports.

While policy comparison is somewhat natural for policy languages based on description logics, it becomes rather difficult for rule-based policies. When policies have recursive rules, the problem is in general undecidable. Still most policies require some form of recursion to model-say-subject and object hierarchies, and certificate chains. In this paper, we show how policies with recursion can be compared by adapting query optimization techniques developed for the relational algebra. We prove soundness and completeness of our method, discuss the compatibility of the restrictive assumptions we need w.r.t. our reference application scenarios, and report the results of a preliminary set of experiments to prove the practical applicability of our approach.Comparing Rule-Based Policieshttp://www.bibsonomy.org/bibtex/2e15fa4c683856d587e1f99feae1d24d6/claudia.wagnerclaudia.wagner2009-03-01T00:00:20+01:00imported <span class="authorEditorList"><a href="/author/Kagal">Lalana Kagal</a>, <a href="/author/Paolucci">Massimo Paolucci</a>, <a href="/author/Srinivasan">Naveen Srinivasan</a>, <a href="/author/Denker">Grit Denker</a>, <a href="/author/Finin">Tim Finin</a>, and <a href="/author/Sycara">Katia Sycara</a> </span><em>IEEE Intelligent Systems</em> <em>19(4):50--56</em> (<em>2004</em>)Sun Mar 01 00:00:20 CET 2009Piscataway, NJ, USAIEEE Intelligent Systems450--56Authorization and Privacy for Semantic Web Services192004imported This article addresses the security of Semantic Web Services that are declaratively described in OWL-S. The authors propose ontologies to annotate OWL-S input and output parameters with respect to their security characteristics, including encryption and digital signatures. They incorporate privacy and authentication policies into OWL-S descriptions and requester profiles. The authors have designed and implemented algorithms to check policy compliance and integrated them in the OWL-S Matchmakerýs service selection process. They also discuss extending the OWL-S VM with features for encrypting and signing messages exchanged between a service requester and provider.Authorization and Privacy for Semantic Web Serviceshttp://www.bibsonomy.org/bibtex/2f243f7aa9f1d2b54eb05a1f78cc138bf/claudia.wagnerclaudia.wagner2009-02-16T10:34:05+01:00imported <span class="authorEditorList"><a href="/author/Breslin">John G.

At present, online communities are islands that are not interlinked. We describe different types of online communities and tools that are currently used to build and support such communities. Ontologies and Semantic Web technologies offer an upgrade path to providing more complex services. Fusing information and inferring links between the various applications and types of information provides relevant insights that make the available information on the Internet more valuable. We present the SIOC ontology which combines terms from vocabularies that already exist with new terms needed to describe the relationships between concepts in the realm of online community sites.

As the Semantic Web unfolds, we feel there are two questions worth posing: (1) do blog entries have semantic structure that can be usefully captured and exploited? (2) is blogging a natural way to encourage growth of the Semantic Web? We explore empirical evidence for answering these questions in the affirmative and propose means to bring blogging into the mainstream of the Semantic Web, including ontologies that extend the RSS 1.0 specification and an XSL transform for handling RSS 0.9x/2.0 files. To demonstrate the validity of our approach we have constructed a semantic blogging environment based on Haystack. We argue that with tools such as Haystack, semantic blogging will be an important paradigm by which metadata authoring will occur in the future.

Indeed, our ultimate goal is to specify a number of criteria, which Semantic Webapplications ought to satisfy, if we want to move away from conventional semantic systems and develop a new generation of Semantic Web applications, which can succeed in applying semantic technology to the challenging context provided by the World-Wide-Web.SpringerLink - Buchkapitelhttp://www.bibsonomy.org/bibtex/29eedeaba17bef692ebde27bd2b71f82e/claudia.wagnerclaudia.wagner2008-12-21T11:22:35+01:00networks social <span class="authorEditorList"><a href="/author/Mika">Peter Mika</a> </span><em>Springer-Verlag New York, Inc., </em><em>Secaucus, NJ, USA, </em>(<em>2007</em>)Sun Dec 21 11:22:35 CET 2008Secaucus, NJ, USASocial Networks and the Semantic Web (Semantic Web and Beyond)2007networks social Social Networks and the Semantic Web (Semantic Web and Beyond)http://www.bibsonomy.org/bibtex/23804dfae65c021d12b1fc01b0405fdd5/claudia.wagnerclaudia.wagner2008-12-21T10:39:07+01:00networks semantic social <span class="authorEditorList"><a href="/author/Breslin">John Breslin</a>, and <a href="/author/Decker">Stefan Decker</a> </span><em>IEEE Internet Computing</em> <em>11(6):86--90</em> (<em>2007</em>)Sun Dec 21 10:39:07 CET 2008Piscataway, NJ, USAIEEE Internet Computing686--90The Future of Social Networks on the Internet: The Need for Semantics112007networks semantic social The Future of Social Networks on the Internethttp://www.bibsonomy.org/bibtex/22e7585e46240857d29794fb585e398eb/claudia.wagnerclaudia.wagner2008-12-08T10:13:51+01:00DERI dataset semanticweb sioc socialnetworks <span class="authorEditorList"><a href="/author/Bojars">U.
