Implementing an Agent Negotiation Protocol based on Persuasion

In this paper, we present methods for improving problems in group decision-making and implement a meeting scheduling system. This system automatically schedules meetings based on users' calendars. In the system, agents negotiate on behalf of the users. The problem is that the agent must clarify the trade-o between \reaching a consensus" and \re ecting the users' preferences." We improve the trade-o by using the persuasion protocol and by controlling negotiation among agents by means of the e ective characteristic function. Meeting scheduling system In our meeting scheduling system(Ito & Shintani 1996), an agent is assigned to a user. Each user manages a private calendar. To schedule a meeting, agents negotiate using the users' private calendars. Users input information on private events into their calendars and also can attach a weight to an event. This weight is represented by a numerical value.
