WISE: A World Wide Web Resource Database System

noindent This paper describes the World Wide Web Index and Search Engine (WISE) for resource discovery. The system is designed around a resource database containing meta-information about WWW resources and is automatically built using an indexer robot, a special WWW client agent. The resource database allows users to search for resources based on keywords, and to learn about potentially relevant resources without having to directly access them. Such capabilities can signiicantly reduce the amount of time that a user needs to spend in order to nd the information of his/her interest. The main strength of WISE is its use of advanced information retrieval techniques. The paper discusses WISE's main components: the resource database, the indexer robot, the search engine, and the user interface, and discusses the issues involved in the design, implementation and evaluation of the system.
