  • 2LIP: Filling the Gap between the Current and the Three-Dimensional Web 

    Jankowski, Jacek; Decker, Stefan (2009)
    In this article we present a novel approach, the 2-Layer Interface Paradigm (2LIP), for designing simple yet interactive 3D web applications, an attempt to marry advantages of 3D experience with the advantages of the ...
  • Approximating Query Completeness by Predicting the Number of Answers in DHT-based Web Applications 

    Karnstedt, Marcel; Hauswirth, Manfred; Sapkota, Brahmananda (2008)
  • A Context Lifecycle For Web-Based Context Management Services 

    Hynes, Gearoid; Reynolds, Vinny; Hauswirth, Manfred (2009)
    During the development of context aware applications a con- text management component must traditionally be created. This task re- quires specialist context lifecycle management expertise and hence can be a significant ...
  • Decomposing Discussion Forums using User Roles 

    Chan, Jeffrey; Hayes, Conor (, 2010)
    Discussion forums are a central part of Web 2.0 and Enterprise 2.0 infrastructures. The health and sustainability of forums is dependent on the information exchange behaviour of its members. Such behaviour needs to be ...
  • Embedding non-ground logic programs into autoepistemic logic for knowledge base combination 

    Polleres, Axel (2011)
    In the context of the Semantic Web, several approaches to the combination of ontologies, given in terms of theories of classical first-order logic and rule bases, have been proposed. They either cast rules into classical ...
  • Establishing a distributed system for the simple representation and integration of diverse scientific assertions 

    Samwald, Matthias; Stenzhorn, Holger (Biomed Central, 2011)
    Information technology has the potential to increase the pace of scientific progress by helping researchers in formulating, publishing and finding information. There are numerous projects that employ ontologies and Semantic ...
  • Eye of the Tiger 

    Novacek, Vit; Groza, Tudor; Handschuh, Siegfried; Decker, Stefan (2009)
  • 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 ...
  • Invited Talk: Can We Deal with Emergent Knowledge Yet? 

    Novacek, Vit (VSE Prague, 2010)
    This overview paper briefly describes problems we need to tackle if we want to meaningfully and efficiently process emergent knowledge. By this term we essentially mean knowledge continually emerging in a bottom-up manner ...
  • Learning from Linked Open Data Usage: Patterns & Metrics 

    Möller, Knud; Hausenblas, Michael; Cyganiak, Richard; Handschuh, Siegfried (2010)
    Although the cloud of Linked Open Data has been growing continuously for several years, little is known about the particular features of linked data usage. Motivating why it is important to understand the usage of Linked ...
  • Linked Open Data in Sensor Data Mashups 

    Phuoc, Danh Le; Hauswirth, Manfred (CEUR, 2009)
    Sensors and the real-time data they produce are novel sources of information which need to be integrated into the Semantic Web at very large scale. Most of the time such data is locked inside specific applications and only ...
  • On the efficiency of joining group patterns in SPARQL queries 

    Sierra, Javier; Polleres, Axel (2010)
    In SPARQL, conjunctive queries are expressed by using shared variables across sets of triple patterns, also called basic graph patterns. Based on this characterization, basic graph patterns in a SPARQL query can be ...
  • Relaxing the Basic KR&R Principles to Meet the Emergent Semantic Web 

    Novacek, Vit (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 web reasoning using logic programming techniques 

    Lukácsy, Gergely (2009)
    One of the key issues for the uptake of the Semantic Web idea is the availability of reasoning techniques that are usable on a large scale and that offer rich modeling capabilities by providing comprehensive coverage of ...
  • Towards Cross-Community Effects in Scientific Communities 

    Karnstedt, Marcel; Hayes, Conor (2009)
    Community effects on the behaviour of individuals, the community itself and other communities can be observed in a wide range of applications. This is true in scientific research, where communities of researchers have ...
  • 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 ...
  • Understanding Linked Open Data as a Web-Scale Database 

    Hausenblas, Michael; Karnstedt, Marcel (2010)
    While Linked Open Data (LOD) has gained much attention in the recent years, requirements and the challenges concerning its usage from a database perspective are lacking. We argue that such a perspective is crucial for ...
  • Visual Abstraction and Ordering in Faceted Browsing of Text Collections 

    Thai, VinhTuan; Handschuh, Siegfried (2010)
    While faceted navigation interfaces can assist users in exploring an information collection, there is yet little support for users in choosing a relevant item from the set of items returned from a filtering process. In ...
  • 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; ...
