Many studies have been actively carried out in a distributed processing environment by using agent systems for efficient network management. Multi-agent systems promote the efficiency in solving problems by cooperating among agents. Also, each agent independently manages its own tasks by dividing a whole work into smaller units and assigning them to each agent. There are many application areas in the real world using the multi agent systems. One of these areas is a digital library system. The introduced literatures about the personalized digital library systems consider the topic of papers for analyzing the users' preferred papers. In this case, they can not recommend the papers whose topic is not relevant to the queried keywords request by a user but contents are relevant to them. In order to solve the problem, I consider the abstracts in the papers for providing a personalized paper search list according to the users' behavior on the papers and the relevance among keywords in the abstracts. Also, the problem from the multi agent-based digital library systems is that users themselves should visit all possible search servers one by one. To overcome the problems, a new platform of multi-agent digital library system which is mobile search system is proposed here. Users do not need to visit all possible search servers with the same query by using the new platform. The proposed system automatically visits to all possible search servers when user requests a query. In this case, the scheduling of visiting the search servers is needed. Also, the negotiation for the results searched from the servers needs to be made for complicated situations such as the duplicated search results from multiple servers. Also, the proposed personalized paper search algorithm builds users' individual relevance network from analyzing the appearance frequencies of keywords in the searched papers. The relevance network is personalized by providing weights to the appearance frequencies of keywords according to users' behaviors on the searched list, such as 'downloading,' 'opening,' and 'no-action'. From the experimental results, it is demonstrated the proposed method using 100 faculties' search information employed in the University of Suwon. Also, the performance of the proposed method is compared with that of the conventional paper search system by surveying the satisfaction of users for both systems.
