  • Design and analysis of an efficient distributed event notification service

    Bittner, Sven; Hinze, Annika (2004-01-01)
    Event Notification Services (ENS) use the publish/subscribe paradigm to continuously inform subscribers about events they are interested in. Subscribers define their interest in so-called profiles. The event information ...
  • Open issues in semantic query optimization in relational DBMS

    Genet, Bryan Howard; Hinze, Annika (2004-01-01)
    After two decades of research into Semantic Query Optimization (SQO) there is clear agreement as to the efficacy of SQO. However, although there are some experimental implementations there are still no commercial ...
  • Contrasting object-relational and RDF modelling in a Tourist Information System

    Hinze, Annika; Loeffler, Katja; Voisard, Agnès (2004)
    Advanced tourist information systems should deliver more than weakly-related static information about sights. Instead, semantically-rich information about sights (e.g., groups of sights with same characteristics) should ...
  • Summer Universities for Women in Computer Science

    Oechtering, Veronika; Alder, Simone; Jolk, Friederike; Klempien-Hinrichs, Renate; Sohle, Bettina; Oelinger, Maria; Kreuzeder, Alexandra; Stiftinger, Anna; Hinze, Annika (2004)
    A cross-university approach will be discussed that reflects moneducation, networking, and gender oriented organizational reforms in university programs. The concept was developed in Germany in 1997 as a national approach. ...
  • Trust and reputation in dynamic scientific communities

    Rana, Omer F.; Hinze, Annika (IEEE Educational Activities Department, Piscataway, NJ, USA, 2004)
    The formation of collaboration networks (or communities) is an important latent effect in many computational science undertakings. Generally, collaboration networks bring together participants who wish to achieve some ...
  • Classification and analysis of distributed event filtering algorithms

    Bittner, Sven; Hinze, Annika (Springer, Berlin, 2004)
    Publish/subscribe middleware provides efficient support for loosely coupled communication in distributed systems. A number of different distributed message-filtering algorithms have been proposed. So far, a systematic ...
  • A Meta-Service for Event Notification

    Jung, Doris; Hinze, Annika (Spring, Berlin, 2004)
    The integration of event information from diverse event notification sources is, as with meta-searching over heterogeneous search engines, a challenging task. Due to the complexity of event filter languages, known solutions ...
  • Efficient filtering of composite events

    Hinze, Annika (Springer, Berlin, 2003)
    Event Notification Services (ENS) are used in various applications such as remote monitoring and control, stock tickers, traffic control, or facility management. The performance issues of the filtering of primitive events ...
  • Storing RDF as a Graph

    Bönström, Valerie; Hinze, Annika; Schweppe, Heinz (IEEE Computer Society, Washington, DC, USA, 2003)
    RDF is the first W3C standard for enriching information resources of the Web with detailed meta data. The semantics of RDF data is defined using a RDF schema. The most expressive language for querying RDF is RQL, which ...
  • Location- and time- based information delivery in tourism

    Hinze, Annika; Voisard, Agnès (Springer, Berlin, 2003)
    Today s mobile devices allow end users to get information related to a particular domain based on their current location, such as the fastest route to the nearest drugstore. However, in such Location-Based Services (LBS), ...
