Title

Discovering user access patterns on the World Wide Web

Source

Knowledge-based systems. 10(1998) no.7, S.463-470

Year

Abstract

Intelligent agents should be used to assist users of the WWW. Identifies a number of key components in such a system and proposes a system architecture. Designs a learning agent along with the underlying algorithms for the discovery of areas of interest from user access logs. The discovered topics can be used to improve the efficiency of information retrieval by prefetching documents for the users and storing them in a document database in the system. Implements a prototype system
