    • ReConRank: A Scalable Ranking Method for Semantic Web Data with Context 

      Hogan, Aidan; Harth, Andreas; Decker, Stefan (2006)
      We present an approach that adapts the well-known PageRank/HITS algorithms to Semantic Web data. Our method combines ranks from the RDF graph with ranks from the context graph, i.e. data sources and their linkage. We present ...
    • 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 ...
    • SWSE: Answers Before Links! 

      Harth, Andreas; Hogan, Aidan; Delbru, Renaud; Umbrich, Jürgen; O'Riain, Sean; Decker, Stefan (CEUR-WS.org, 2007)
      We present a system that improves on current document- centric Web search engine technology; adopting an entity-centric perspective, we are able to integrate data from both static and live sources into a coherent, interlinked ...
    • Aiding the Data Integration in Medicinal Settings by Means of Semantic Technologies 

      Nováček, Vít; Handschuh, Siegfried (Semantic Technology Institutes International, 2007)
      The paper introduces basic features of a novel ontology integration framework that explicitly takes the dynamics and data-intensiveness of many practical application scenarios into account. We motivate our research partially ...
    • 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 ...
    • A lookup index for Semantic Web resources 

      Oren, Eyal; Tummarello, Giovanni (2007)
      Developers of Semantic Web applications face a challenge with respect to the decentralised publication model: where to find statements about encountered resources. The ¿linked data¿ approach, which mandates that resource ...
    • Towards Fine-grained Service Matchmaking by Using Concept Similarity 

      Polleres, Axel (2007)
      Several description frameworks to semantically describe and match services on the one hand and service requests on the other have been presented in the literature. Many of the current proposals for defining notions of ...
    • 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 ...
    • Collaboration on the Social Semantic Desktop 

      Groza, Tudor; Handschuh, Siegfried (2007)
      To accomplish the daily work people use several desktop applications to collaborate with co-workers. Each application is specialized on a specific domain, such as document management, email, or time planning. Although the ...
    • Towards a social provenance model for the Web 

      Harth, Andreas; Polleres, Axel; Decker, Stefan (2007)
      In this position paper we firstly present the established notion of provenance on the Semantic Web (also referred to as named graphs or contexts), and secondly argue for the benefit of adding to the pure technical notion ...
    • Semi-automatic Integration of Learned Ontologies into a Collaborative Framework 

      Nováček, Vít; Handschuh, Siegfried (2007)
      The paper presents a novel ontology lifecycle scenario that explicitly takes the dynamics and data-intensiveness of real world applications into account. Changing and growing knowledge is handled by semi-automatic ...
    • 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 ...
    • 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 ...
    • Who the FOAF knows Alice? A needed step towards Semantic Web Pipes 

      Polleres, Axel; Tummarello, Giovanni (2007)
      In this paper we take a view from the bottom to RDF(S) reasoning. We discuss some issues and requirements on reasoning towards effectively building SemanticWeb Pipes, aggregating RDF data from various distributed sources. ...

      Kruk, Sebastian Ryszard; Woroniecki, Tomasz; Gzella, Adam; Dabrowski, Maciej (2007)
      JeromeDL is a Semantic Digital Library engine. It uses SemanticWeb and Social Networking technologies to improve browsing and searching for resources. With JeromeDL¿s social and semantic services every library user ...
    • 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 ...
    • 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 ...
