Research on Web Information Extraction System Based-on Multi-Agent Cooperation

摘要

The aim of Web information extraction is to explore usable information,to mine the implied data schema,and to restore the knowledge in the database.The paper firstly analyzes the currentsituation of the research of information extraction, and then proposes the architecture of information extraction system based on multi-agent cooperation. Moreover, this paper introduces the characteristics of each part in the model and shows the process of information extraction.In this model based on multi-agent cooperation,the complexity between task transitions is reduced effectively.
