    Oren, Eyal; Delbru, Renaud; Möller, Knud; Handschuh, Siegfried (2006)
    Semantic Wikis allow users to semantically annotate their Wiki content. The particular annotations can differ in expressive power, simplicity, and meaning. We present an elaborate conceptual model for semantic annotations, ...
  • Approximating Query Completeness by Predicting the Number of Answers in DHT-based Web Applications 

    Karnstedt, Marcel; Hauswirth, Manfred; Sapkota, Brahmananda (2008)
  • Browsing Linked Data with Fenfire 

    Hastrup, Tuukka; Cyganiak, Richard; Bojars, Uldis (2008)
    A wealth of information has recently become available as browsable RDF data on the Web, but the selection of client applications to interact with this Linked Data remains limited. We show how to browse Linked Data with ...
  • Converging Web and Desktop Data with Konduit 

    Dragan, Laura; Möller, Knud; Handschuh, Siegfried; Ambrus, Oszkar (2009)
    In this paper we present Konduit, a desktop-based platform for visual scripting with RDF data. Based on the idea of the semantic desktop, non-technical users can create, manipulate and mash-up RDF data with Konduit, and ...
  • A Conversation-oriented language for B2B integration based on Semantic Web Services 

    Gomez, Juan Miguel; Haller, Armin; Bussler, Christoph (2005)
    Establishing conversations in a B2B environment has significantly eased since the advent of standards such as RosettaNet and ebXML. These standardisation efforts have maintained some flexibility in defining interactions ...
  • Data and Process Mediation Support for B2B Integration 

    Zaremba, Maciej; Herold, Maximilian; Zaharia, Raluca; Vitvar, Tomas (2008)
    In this paper we present how Semantic Web Service technology can be used to overcome process and data heterogeneity in a B2B integration scenario. While one partner uses standards like RosettaNet for product purchase and ...
  • DigiMe - Ubiquitous Search and Browsing for Digital Libraries 

    Kruk, Sebastian Ryszard; Grzonkowski, Slawomir; Gzella, Adam; Cygan, Mariusz (IEEE, 2006)
    Vast sources of information, such as the Internet are difficult to browse and/or search through. Existing tools can be sometimes frustrating for many people. So far a number of techniques have been proposed to deliver ...
  • DING! Dataset Ranking using Formal Descriptions 

    Toupikov, Nickolai; Umbrich, Jürgen; Delbru, Renaud; Hausenblas, Michael; Tummarello, Giovanni (2009)
    Considering that thousands if not millions of linked datasets will be published soon, we motivate in this paper the need for an efficient and effective way to rank interlinked datasets based on formal descriptions of their ...
  • dlvhex-sparql: A SPARQL-compliant query engine based on dlvhex 

    Polleres, Axel (CEUR, 2007)
    This paper describes the dlvhex SPARQL plugin, a query processor for the upcoming Semantic Web query language standard by W3C. We report on the implementation of this languages using dlvhex, a flexible plugin system ...
  • Enabling Trust and Privacy on the Social Web 

    Passant, Alexandre; Hausenblas, Michael; Polleres, Axel; Decker, Stefan (2009)
  • The ExpertFinder Corpus 2007 for the Benchmarking and Development of ExpertFinding Systems 

    Hogan, Aidan; Harth, Andreas (2007)
    We provide a benchmark dataset for expert finding within the computer science domain. We show how large isolated data graphs from disparate structured data sources can be combined to form one, large, well-linked RDF graph ...
  • Exposing Semantic Web Service principles in SOA to solve EAI scenarios 

    Haller, Armin; Gomez, Juan Miguel; Bussler, Christoph (2005)
    Traditional Enterprise Application Integration (EAI) focuses on the integration of application interfaces by pipelining different middle- ware technologies like message queuing or remote method invocations. Web Service ...
  • Fast and Scalable Pattern Mining for Media-Type Focused Crawling 

    Umbrich, Jürgen; Karnstedt, Marcel; Harth, Andreas (2009)
    Search engines targeting content other than hypertext documents require a crawler that discovers resources identifying files of certain media types. Naive crawling approaches do not guarantee a sufficient supply of new ...
  • From Online Community Data to RDF 

    Bojars, Uldis; Breslin, John (2007)
    Large amounts of data are created within online community sites (forums, blogs, etc.). These can serve as a valuable source of information for web users, and usually contain rich meta-information. Most of this information ...
  • Harvesting Desktop Data for Semantic Blogging 

    Möller, Knud; Decker, Stefan (2005)

  • Leveraging existing web frameworks for a SIOC explorer to browse online social communities 

    Heitmann, Benjamin; Oren, Eyal (2007)
    Since online SemanticWeb applications are based on existing Web infrastructure, developing these applications could leverage experiences with and infrastructure of existing frameworks. These frameworks need to be extended ...
  • A Logical Framework for Web Service Discovery 

    Polleres, Axel; Keller, Uwe; Fensel, Dieter (IEEE, 2004)
    Current technologies for Web Services are based on syntactical descriptions and, therefore, lend themselves to only limited amount of automation. Research efforts in Semantic Web Services, such as WSMO, try to overcome ...
  • A lookup index for Semantic Web resources
