  • 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 ...
  • ReVeaLD: A user-driven domain-specific interactive search platform for biomedical research 

    Kamdar, Maulik; Hasnain, Ali; Decker, Stefan; Deus, Helena F. (2013)
  • A Roadmap for navigating the Life Sciences Linked Open Data Cloud 

    Hasnain, Ali; Sana e Zainab, Syeda; Kamdar, Maulik; Mehmood, Qaiser; Deus, Helena; Mehdi, Muntazir; Decker, Stefan (2014)
    Multiple datasets that add high value to biomedical research have been exposed on the web as a part of the Life Sciences Linked Open Data (LSLOD) Cloud. The ability to easily navigate through these datasets is crucial for ...
  • Semantic Social Collaborative Filtering with FOAFRealm 

    Kruk, Sebastian Ryszard; Decker, Stefan (2005)
    The most popular collaborative filtering implementations require either a critical mass of referenced resources and a lot of active users. Other solutions are based on finding a referral with an expertise on the given ...
  • Semantic Wikis for Personal Knowledge Management 

    Oren, Eyal; Breslin, John; Decker, Stefan (Springer, 2006)
    Wikis are becoming popular knowledge management tools. Analysing knowledge management requirements, we observe that wikis do not fully support structured search and knowledge reuse. We show how Semantic wikis address the ...
  • Simple algorithms for predicate suggestions using similarity and co-occurrence 

    Oren, Eyal; Gerke, Sebastian; Decker, Stefan (Association for Computing Machinery, 2007)
    When creating Semantic Web data, users have to make a critical choice for a vocabulary: only through shared vocabularies can meaning be established. A centralised policy prevents terminology divergence but would restrict ...
  • Sindice Widgets: Lightweight embedding of Semantic Web capabilities into existing user applications 

    Westerski, Adam; Iqbal, Aftab; Tummarello, Giovanni; Decker, Stefan (2008)
    In this paper we present a methodology by which it is possible to enhance existing web applications and directly deliver to the end users aggregated ¿views¿ of information. These views are accessed by clicking on buttons ...
  • 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 Networking Portals: An Overview and Evaluation 

    O'Murchu, Ina; Breslin, John; Decker, Stefan (2004)
    Next generation communication on the Internet changes the way we interact with the complexity of the information load on the World Wide Web. Web portals act as gateways to resources and a multitude of services on the ...
  • 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 ...
  • 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 ...
  • 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 ...
  • TopFed: TCGA tailored federated query processing and linking to LOD 

    Padmanabhuni, Shanmukha S.; Iqbal, Aftab; Decker, Stefan (BioMed Central, 2014-12-03)
    Backgroud: The Cancer Genome Atlas (TCGA) is a multidisciplinary, multi-institutional effort to catalogue genetic mutations responsible for cancer using genome analysis techniques. One of the aims of this project is to ...
  • 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 ...
  • Towards Dataset Dynamics: Change Frequency of Linked Open Data Sources 

    Umbrich, Jürgen; Hausenblas, Michael; Hogan, Aidan; Polleres, Axel; Decker, Stefan (CEUR, 2010)
    Datasets in the LOD cloud are far from being static in their nature and how they are exposed. As resources are added and new links are set, applications consuming the data should be able to deal with these changes. In ...
  • Towards Lightweight and Robust Large Scale Emergent Knowledge Processing 

    Novacek, Vit; Decker, Stefan (Springer, 2009)
    We present a lightweight framework for processing uncertain emergent knowledge that comes from multiple resources with varying relevance. The framework is essentially RDF-compatible, but allows also for direct representation ...
  • Weaving the Pedantic Web 

    Hogan, Aidan; Harth, Andreas; Passant, Alexandre; Decker, Stefan; Polleres, Axel (CEUR, 2010)
    Over a decade after RDF has been published as a W3C recommendation, publishing open and machine-readable content on the Web has recently received a lot more attention, including from corporate and governmental bodies; ...
  • YARS2: A Federated Repository for Querying Graph Structured Data from the Web 

    Harth, Andreas; Umbrich, Jürgen; Hogan, Aidan; Decker, Stefan (2007)
    We present the architecture of an end-to-end semantic search engine that uses a graph data model to enable interactive query answering over structured and interlinked data collected from many disparate sources on the Web. ...
