    • notitio.us - Semantic Information Discovery, Browsing and Sharing 

      Gzella, Adam; Kruk, Sebastian Ryszard (2007)
      Searching for information on the Internet became much easier when Google started delivering their service. We got used to getting the most important (probably) results on the top of the list. But more and more ...
    • Towards Constraint-Based Composition With Incomplete Service Descriptions 

      Moran, Matthew; Vitvar, Tomas; Zaremba, Maciej (IEEE, 2007)
      We apply our work on Web service discovery with initially incomplete information to the problem of service com- position. Rich semantic descriptions of Goals and Web ser- vices allow the unambiguous specification of ...
    • 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 ...
    • What should an ASP solver output? A multiple position paper 

      Polleres, Axel (May, 2007)
      This position paper raises some issues regarding the output of solvers for Answer Set Programming and discusses experiences made in several different settings. The first set of issues was raised in the context of the ...
    • Processing ontology alignments with SPARQL 

      Polleres, Axel (IEEE, 2008)
      Solving problems raised by heterogeneous ontologies can be achieved by matching the ontologies and processing the resulting alignments. This is typical of data mediation in which the data must be translated from one ...
    • Neologism: Easy Vocabulary Publishing 

      Basca, Cosmin; Corlosquet, Stéphane; Cyganiak, Richard; Fernández, Sergio; Schandl, Thomas (2008)
      Creating, documenting, publishing and maintaining an RDF Schema vocabulary is a complex, timeconsuming task. This makes vocabulary maintainers reluctant to evolve their creations quickly in response to user feedback; it ...
    • Social Networks and Data Portability using Semantic Web technologies 

      Bojars, Uldis; Breslin, John; Decker, Stefan (2008)
      Social network and data portability has recently gained a lot of interest as one of the issues for social media sites on the Web. In this paper, we will show how Semantic Web technologies and especially the FOAF and ...
    • Relaxing the Basic KR&R Principles to Meet the Emergent Semantic Web 

      Nováček, Vít (CEUR-WS, 2008)
      The paper argues for an alternative, empirical (instead of analytical) approach to a Semantic Web-ready KR&R, motivated by the so far largely untackled need for a feasible emergent content processing.
    • Scalable Authoritative OWL Reasoning on a Billion Triples 

      Hogan, Aidan; Harth, Andreas; Polleres, Axel (2008)
      In this paper we present a scalable algorithm for performing a subset of OWL reasoning over web data using a rule-based approach to forward-chaining; in particular, we identify the problem of ontology hijacking: new ...
    • SWSE: Objects before documents! 

      Harth, Andreas; Hogan, Aidan; Umbrich, Jürgen; Decker, Stefan (2008)
      Web search engines are immensely useful for locating documents online. However, with more and more structured data being published online, the restriction to the hyperdocument model impairs the usefulness for searching and ...
    • Approximating Query Completeness by Predicting the Number of Answers in DHT-based Web Applications 

      Karnstedt, Marcel; Hauswirth, Manfred; Sapkota, Brahmananda (2008)
    • inContext: A Pervasive and Collaborative Working Environment for Emerging Team Forms 

      Polleres, Axel (2008)
      Participants in current team collaborations belong to different organizations, work on multiple objectives at the same time, and frequently change locations. They use different devices and infrastructures in collaboration ...
    • 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 ...
    • Processing ontology alignments with SPARQL 

      Polleres, Axel (IEEE Computer Society, 2008)
    • Microblogging: A Semantic Web and Distributed Approach 

      Passant, Alexandre; Hastrup, Tuukka; Bojars, Uldis; Breslin, John (2008)
      While microblogging has quickly gained a lot of interest in the Web 2.0 community, it still has not been leveraged to the Semantic Web unlike blogs and wikis. This paper describes the features, methods and architecture of ...
    • Weaving SIOC into the Web of Linked Data 

      Bojars, Uldis; Passant, Alexandre; Cyganiak, Richard; Breslin, John (2008)
      Social media sites can act as a rich source of large amounts of data by letting anyone easily create content on the Web. The SIOC ontology and tools developed for it allow us to express this information as interlinked RDF ...
    • World of WebCraft - Mashing up World of Warcraft and the Web 

      Möller, Knud (2008)
      This short paper presents World of WebCraft, a set of tools which together allow players of the MMORPG World of Warcraft to generate photoblog-like Web representations of their in-game avatars. This is achieved by periodically ...
    • 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 ...
    • EUREEKA: Deepening the Semantic Web by More Efficient Emergent Knowledge Representation and Processing 

      Nováček, Vít (CEUR-WS, 2008)
      One of the major Semantic Web challenges is the knowledge acquisition bottleneck. New content on the web is produced much faster than the respective machine readable annotations, while a scalable knowledge extraction ...
    • Anatomy of a Semantic Virus 

      Nasirifard, Peyman (2008)
      In this position paper, I discuss a piece of malicious automated software that can be used by an individual or a group of users for submitting valid random noisy RDF-based data based on predefined schemas/ontologies to ...
