  • JeromeDL - a Semantic Digital Library 

    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 ...
  • JeromeDL and FOAFRealm - Taking Advantage of Semantic Social Collaborative Filtering in Digital Libraries 

    Kruk, Sebastian Ryszard; Decker, Stefan (2005)
    In this paper, we present FOAFRealm, a user management library based on social networking and FOAF metadata, and its deployment in JeromeDL, a digital library with semantics. We will demonstrate the most important ...
  • Knowledge Sharing and Filtering on Semantic Web 2.0 

    Kruk, Sebastian Ryszard; Gzella, Adam (2007)
    E-learning and other popular services that grow on the fertile soil of the Internet technologies usually fail to reach their full potential. With new, emerging technologies of the second generation Internet there is even ...
  • 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 ...
  • 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 ...
  • The NEPOMUK Project - On the way to the Social Semantic Desktop 

    Groza, Tudor; Handschuh, Siegfried; Möller, Knud (2007)
    This paper introduces the NEPOMUK project which aims to create a standard and reference implementation for the Social Semantic Desktop. We outline the requirements and functionalities that were identified for a useful ...
  • A Non-traditional Inference Paradigm for Learned Ontologies 

    Novacek, Vit (CEUR Workshop proceedings, 2007)
  • Performing Object Consolidation on the Semantic Web Data Graph 

    Hogan, Aidan; Harth, Andreas; Decker, Stefan (2007)
    An important aspect of Semantic Web technologies is the issue of identity and uniquely identifying resources, which is essential for integrating data across sources. Currently, there is poor agreement on the use of ...
  • Podcast Pinpointer: A Multimedia Semantic Web Application 

    Hogan, Aidan; Harth, Andreas; Breslin, John (IEEE, 2005)
    In late 2004, a new method of publishing multimedia broadcasts on the Internet became popular called `Podcasting¿. Podcasting incorporates existing feed description formats, namely RSS 2.0, to ...
  • Previewing Semantic Web Pipes 

    Phuoc, Danh Le; Polleres, Axel; Samwald, Matthias; Tummarello, Giovanni (Springer, 2008)
    In this demo we present a first implementation of Semantic Web Pipes, a powerful tool to build RDF-based mashups. Semantic Web pipes are defined in XML and when executed they fetch RDF graphs on the Web, operate on them, ...
  • A Prototype to Explore Content and Context on Social Community Sites 

    Bojars, Uldis; Heitmann, Benjamin; Oren, Eyal (2007)
    The SIOC Ontology can be used to express information from the online community sites in a machine readable form using RDF. This rich data structure allows us to easily analyse and extract social relations from these ...
  • 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 ...
  • 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 ...
  • Semantic SOA to Promote Integration of Heterogeneous B2B Services 

    Vitvar, Tomas; Moran, Matthew; Zaremba, Maciej; Haller, Armin; Kotinurmi, Paavo (IEEE, 2007)
    Modeling the semantics of business services and their corresponding messages using ontologies enables flexible integration that is more adaptive to business-driven change. In this paper we demonstrate our approach building ...
  • Semantic Web Services enabled B2B Integration 

    Kotinurmi, Paavo; Vitvar, Tomas; Haller, Armin (2006)
    The use of Semantic Web Service (SWS) technologies have been suggested to enable more dynamic B2B integration of heterogeneous systems and partners. We present our approach to accomplish dynamic B2B integrations based on ...
  • SESA: Emerging Technology for Service-Centric Environments 

    Vitvar, Tomas; Zaremba, Michal; Zaremba, Maciej; Moran, Matthew; Fensel, Dieter (Institute of Electrical and Electronics Engineers, 2007)
    Service-oriented architectures - and particularly the Web service technologies that enable them, such as WSDL (Web Services Description Language) and SOAP - are widely acknowledged for their potential to revolutionize ...
  • SIOC: Content Exchange and Semantic Interoperability Between Social Networks 

    Breslin, John; Bojars, Uldis; Passant, Alexandre; Fernández, Sergio; Decker, Stefan (2009)
    This paper describes work performed during the last few years in the context of the SIOC project in order to model social data on the Web using Semantic Web technologies. We will give an overview of the SIOC model, ...
  • 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 ...
  • SPARQL++ for mapping between RDF vocabularies 

    Polleres, Axel (Springer, 2007)
    Lightweight ontologies in the formof RDF vocabularies such as SIOC, FOAF, vCard, etc. are increasingly being used and exported by ¿serious¿ applications recently. Such vocabularies, together with query languages like SPARQL ...
