The aim of this research is to develop a personal assistant system based on multi-agent model. The achieved research results are as follows.・Design and implementation of KODAMA(Kyushu University Open and Distributed, Autonomous Multi Agents) system. KODAMA consists of logical and physical agent world. They are Agent community and ACZ(Agent Communication Zone), respectively. At KODAMA system, an agent community is also regarded as one agent, called a portal agent of the community. The concept of both agent community and a portal agent enables to construct a hierarchical logical agent world. In this logical agent world, agents can communicate with another agent using only their own communication language without considering another agent's physical address and any physical communication protocol and method.・Development of a WebKODAMA system. The WebKODAMA system is a Web retrieval system specialized to the user. The system can find the preferences and interests of the user according to his/her query and book-mark history, and observe his/her implicit and explicit responses.
