    An Ontology-Based Recommendation System for Elderly and Disabled Persons
    (10. GI-Workshop "Adaptivität und Benutzermodellierung in interaktiven Softwaresystemen", 2002) Zinnikus, Ingo; Bogdanovich, Anton; Schäfer, Ralph
    In this paper, we describe the use of a hierarchical ontology representation as a basis for modelling user preferences in the SAID project for elderly and disabled persons. The nodes of the ontology tree are associated with either pre-selected or dynamically found web sites relevant for each topic of the user s interest (in this way web-surfing can be substituted by browsing through the ontology). In order to further reduce the complexity of the tree, we combine this approach with applying a probability based recommendation system which monitors the user s actions and adapts itself according to the observed behaviour. We also show that the resulting ontology tree is compatible with Bayesian networks and discuss limitations and possible extensions.

    Modelling actors and stories in web information systems
    (Information systems technology and its applications, 3rd international conference ISTA'2004, 2004) Schewe, Klaus-Dieter; Thalheim, Bernhard; Zlatkin, Sergiy
    The design of web information systems (WISs) requires a clear picture of the intended users and their behaviour. WIS users are called actors and classified according to their roles, intentions and behaviour. This leads to various propositional and deontic constraints on the story space, i.e. the abstract specification of WIS locations and activities associated with them. The knowledge obtained from the modelling of actors can be used to personalise the story space to the needs of a particular actor.
