The User Model and Context Ontology GUMO Revisited for Future Web 2.0 Extensions.

Abstract

Abstract. We revisit the top-level ontology Gumo for the uniform management of user and context models in a semantic web environment. We discuss design decisions, while putting the focus on ontological issues. The structural integration into user model servers, especially into the U2M-UserModel&ContextService, is also presented. We show ubiquitous applications using the user model ontology Gumo together with the user model markup language UserML. Finally, we ask how data from Web 2.0 and especially from a social tagging application like del.icio.us as a basis for user adaptation and context-awareness could influence the ontology.
