Abstract :
To cope with the problem of information overload, various information filtering system have been proposed. However, most of them represent documents and user´s interests as bag of words, and thus the intrinsic structures and semantic information in them are neglected. The information filtering mainly depended on the matching of simple key word or bag of words. In this paper, a multi-agent personalized information filtering system based on XML has been developed, under which heterogeneous, distributed data on the Internet are integrated to XML data, and the similarity of documents to user´s interests is measured using an extended vector space model by which documents and user´s interests are represented as structural vectors taking both content and structure into account. The general architecture of the system is presented and several key technologies for the construction of such a system are also described.
