Abstract

An HTTP based resource discovery system called Discover has been built that provides a single point of access to over 500 WAIS servers. Discover provides 2 key services: query refinement and query routing. Query refinement helps a user improve a query fragment to describe the user's interests more precisely. Once a query has been refined and describes a manageable result set, query routing automatically forewards the query to the WAIS servers that contain relevant documents. Abbreviated descriptions of WAIS sites called content lables are used by the query routing provides an effective way to discover resources in a large universe of documents. Expansion of query fragments is essential in helping one use a large, dynamically changing, heterogenous distributed information system
