    On the construction of a probabilistic model for assessing users' beliefs in an information environment
    (Informatik 2004, Informatik verbindet, Band 2, Beiträge der 34. Jahrestagung der Gesellschaft für Informatik e.V. (GI), 2004) Schwarzkopf, Eric
    We are developing an interaction environment for information portals in which users can create their own personal knowledge bases to store and define relationships between retrieved items. In this paper, we present our approach for combining these personal knowledge bases to a knowledge base for the entire user community that is to be used as part of an automatic recommendation system. We utilize a probabilistic model for assessing how strongly a single user's definition (or lack thereof) of a relationship should influence the system's belief in the relationship. The latter is revised using Pearl's method of uncertain evidence.

    Personalized Interaction with Semantic Information Portals
    (11. GI-Workshop "Adaptivität und Benutzermodellierung in interaktiven Softwaresystemen", 2003) Schwarzkopf, Eric
    We present the conception of a personalized interaction environment for semantic information portals, focusing on the user model maintained in this environment. The environment will support the user in finding documents via the portal, but also in managing and working with these documents once they have been retrieved. The user model is a central, explicit aspect of the user’s interaction with the portal, with immediate access by the system as well as the user. This is made possible by the common semantic concepts avail- able to both parties. The described environment is currently in its early implementation phase. Our ideas and suggestions are presented here as points for discussion at the workshop.

    Semantic methods and tools for information portals
    (INFORMATIK 2003 – Innovative Informatikanwendungen, Band 1, Beiträge der 33. Jahrestagung der Gesellschaft für Informatik e.V. (GI), 2003) Agarwal, Sudhir; Fankhauser, Peter; Gonzalez-Ollala, Jorge; Hartmann, Jens; Hollfelder, Silvia; Jameson, Anthony; Klink, Stefan; Lehti, Patrick; Ley, Michael; Rabbidge, Emma; Schwarzkopf, Eric; Shrestha, Nitesh; Stojanovic, Nenad; Studer, Rudi; Stumme, Gerd; Walter, Bernd; Weber, Alexander
    The paper describes a set of approaches for representing and accessing information within a semantically structured information portal, while offering the possibility to integrate own information. It discusses research performed within the project 'Semantic Methods and Tools for Information Portals (SemI-Port)'. In particular, it focuses on (1) the development of scalable storing, processing and querying methods for semantic data, (2) visualization and browsing of complex data inventories, (3) personalization and agent-based interaction, and (4) the enhancement of web mining approaches for use within a semantics-based portal.
