1 Vol. 44 No. 12 Dec , 3 4 Development and Evaluation of Information Provision System for In-Vehicle Terminal Based on Agent Framework Masanori Hattori, 1 Kenta Cho, 1 Akihiko Ohsuga, 1 Shinichi Honiden 2, 3 and Yoshiaki Fukazawa 4 This paper proposes Ubiquitous Personalize Agent Framework and it s application: Information Provision System for In-Vehicle Terminal. Ubiquitous personalize agent framework is constructed by combining context reasoning framework and lightweight mobile agent platform. This framework can decrease programming cost and response latency of ubiquitous services. Information provision system for in-vehicle terminal is constructed based on the framework. We confirmed the effectiveness of the framework in terms of development cost and response speed Corporate Research & Development Center, TOSHIBA Corporation 2 National Institute of Informatics 3 Graduate School of Information Science and Technology, The University of Tokyo 4 Department of Computer and Information Science, Waseda University LBS Location-Based Service Plangent 1) Bee-gent 2) 3) 4) (1) GPS 3024
