This talk presents the design of a digital library system that integrates conventional digital library services with contemporary WWW advantages, such as comprehensive coverage and agents for information search and selection. We use a user-centered approach and apply data mining techniques in the design of agents for information search and selection. There are various agents in this digital library system to perform different functions. Among them, SiteHelper is a unique agent in our system compared to existing digital library systems. It acts as a housekeeper for the system and as a helper for the users to find relevant information. In order to assist the users in finding relevant information at the centralized location (with Web links to the global Web), SiteHelper interactively and incrementally learns about each user's areas of interest and aids them accordingly, by deploying data mining techniques with incremental learning facilities as its learning and inference engines.

Xindong Wu is a Professor and the Chair of the Department of Computer Science at the University of Vermont, USA, and also a Visiting Chair Professor of Data Mining in the Department of Computing at the Hong Kong Polytechnic University, China. He holds a PhD in Artificial Intelligence from the University of Edinburgh, Britain. His research interests include data mining, knowledge-based systems, and Web information exploration. He has published extensively in these areas in various journals and conferences, including IEEE TKDE, TPAMI, ACM TOIS, DMKD, KAIS, IJCAI, AAAI, ICML, KDD, ICDM, and WWW, as well as 14 books and conference proceedings.
