An XMLBased Multi-Agents Model for Information Retrieval on WWW

Abstract

Abstract: In this paper, we present a multi-agents model for IR, namely IR agents, for information retrieval on WWW. An IR agent consists of three types of agent, Managing agents for extracting the semantics of information and managing the details of co-ordinate agents, Interface agents for interacting between the system and users, and Search agents for discovering the information on WWW. This work focuses on the use of XML technology for information retrieval on WWW. In our model, agents communicate with each other to perform IR tasks by using XML as an agent communication language. They also express their knowledge bases and the semantics of their search results in XML format. As a result, users are able not only to access information more precisely from semantically encoded search results that are returned from our model, but also to utilize the content of the results without using proprietary tags or customized scripts to scrape web pages to extract the content. Key words: Information retrieval, Multi-agents model, XML 1
