Layered agent system architecture for personalized retrieval of information from Internet

The article focuses on the architecture of the agent system designed for personalized data retrieval from the Internet. As a consequence of the explosion of the World Wide Web, an increasing amount of information is stored in repositories all over the Web. We suggest three-layered architecture of the agent system including user side layer, which contains user profile and personalization module, information source layer and an intermediary layer offering accompanying services such as authentication and service registration. Such architecture enables inclusion of different information sources, personalization of search results and later enhancements of the system.
