Online auctions are becoming an increasingly important channel for electronic commerce. There exist more than 150 online auction sites on the Internet. It is difficult for users to attend, monitor, and bid at multiple auction sites simultaneously. In this paper, we propose BiddingBot which is a multi agent system that supports users in attending, monitoring(More)
In this paper, we propose a persuasion mechanism for negotiation among agents for a group decision support system and implement a group choice design support system (GCDSS). GCDSS helps a group decision to make a reasonable choice from alternatives. In the system , each user manages a system for an Analytic Hierarchy Process (AHP) and an agent. Each user(More)
Scheduling meetings is generally difficult in that it attempts to satisfy the preferences of all participants. However, all participants can agree to a schedule in which a portion of their preferences are not satisfied, since preferences are regarded in terms of their relative importance. In this paper, we formalize a meeting scheduling as a Distributed(More)
Volume discount is seen as an effective form of electronic commerce and a promising field for applying agent technologies. In current volume discount mechanisms, items are not allocated efficiently to buyers. Namely, social surplus is not maximum in existing volume discount schemes. To solve this problem, we propose a volume discount mechanism based on the(More)
We present a method for multi-agent negotiation for implementing a distributed meeting scheduler. In the meeting scheduler, an agent negotiates with other agents about making an public schedule by referring user's private schedules and preferences. We propose a new persuasion method for multi-agent negotiation for reflecting private preferences. We call the(More)

Information agents are computational software systems that provides transparent access to many different information sources in the Internet, and to be able to retrieve, analyze, manipulate, and integrate heterogeneous data and information on demand. Mobile agents are an effective choice for many applications to improve latency and band-width of(More)
We have developed Papits, a research support system, that shares research information, such as PDF files of research papers, in computers on networks and classifies the information into research types. Papits users can share various research information and survey the corpora of their particular fields. To develop Papits, we need to design a mechanism to(More)
