ABSTRACT

Personalized service has achieved great success in the field of e-commerce, it is also used to agriculture information service for improving service efficiency, and a key feature in developing successful personalized service is to construct user model that can represent accurately a user’s interests. This paper presents an ontology-based dynamic user modeling approach to construct user model for Chinese crop germplasm resources information system (CGRIS). The proposed user model relies on individual register information, domain ontology and weblog, and this paper mainly deals with the problem of constructing user ontology and how user model is updated dynamically by weblog with time going. The user model is a user-centered design, and reflects the individual needs of the users. Due to the powerful knowledge representation formalism and associated inference mechanisms of ontology, the ontology-based user model provides an effective mechanism to provide targeted service for the users of Chinese crop germplasm resources information system.
