- KonferenzbeitragPersonalization Services for Adaptive Educational Hypermedia(11. GI-Workshop "Adaptivität und Benutzermodellierung in interaktiven Softwaresystemen", 2003) Dolog, Peter; Henze, NicolaThis paper proposes an architecture for providing personalization services for adaptive educational hypermedia. We formalize adaptation functionality in a re-usable way appropriate for the use in the semantic web. We show how to design personalization services that provide re-usable adaptation methods employing semantic web description formats.
- KonferenzbeitragUser and Document Group Approach of Clustering in Tagging Systems(18th Intl. Workshop on Personalization and Recommendation on the Web and Beyond, 2010) Pan, Rong; Xu, Guandong; Dolog, PeterIn this paper, we propose a spectral clustering approach for users and documents group modeling in order to capture the common preference and relatedness of users and documents, and to reduce the time complexity of similarity calculations. In experiments, we investigate the selection of the optimal amount of clusters. We also show a reduction of the time consuming in calculating the similarity for the recommender systems by selecting a centroid first, and then compare the inside item on behalf of each group.
