Research Interests

  • Database and Information Systems
  • Multi-Feature Query Processing
  • User Preferences and Personalization
  • Cognitive User Modeling and Usage Patterns
  • Peer-to-Peer Networks and Distributed Retrieval
  • Digital Libraries and Content Syndication
  • Multimedia Services, Web Services, and Mobile Computing


I have been or still am currently involved in the following research projects:

  • APIS
    APIS stands for Advanced Personalization for Information Services and is an interdisciplinary project between Computer Science and Cognitive Sciences. APIS is trying to foster personalization techniques to enable intuitive preference and profile management for web service discovery, selection and composition.
  • PUMA
    PUMA stands for Personalized Universal Media Access and aims at developing flexible service-oriented archtitectures for accessing multimedia data anywhere anytime from a variety of client devices. The easy maintenance and reusability of basic multimedia services, as well as their complosition to form complex workflows is the focus of the approach.
  • Semantic GrowBag
    The Semantic GrowBag algorithm exploits keywords provided in metadata annotations of digital objects collections to automatically create light-weight topic categorization systems. Using such emergent semantics enables an alternative way to filter large result sets according to the objects' content without the need to manually classify all objects with respect to a pre-specified vocabulary.
  • ViFaChem II
    ViFaChem 2 aims at providing a digital library infrastructure for creating personalized information spaces. The value added services and Scientific Web 2.0 techniques actively support scientists and researchers in retrieval tasks as well as in deriving new knowledge from the collected information.
