THE TECHNOLOGY AND IMPLEMENTATION OF RESOURCE DISCOVERY ON INTERNET

A mass of heterogeneous, distributed, and dynamic information on Internet has resulted in “information overload”. With the flood of information, it has become an important research issue to provide users with effective service of resource discovery on Internet. Search engines attempt to solve this problem, yet their effect are far from satisfying. In this paper, a distributed cooperative strategy for resource discovery on Internet is firstly presented. Then, several key technologies involved in resource discovery are studied, including data model, Web document retrieval, bibliographic retrieval based on Z39.50, and agent\|based user interface. Finally, a system prototype RDSCC is designed to improve the quality of resource discovery on Internet.
