PRISE Search
Z39.50/PRISE 2.0 consists of a minimal Z39.50-1995 UNIX (Solaris) client-server pair and prototype indexing and search engines (PRISE) developed by NIST. The server is designed to isolate the search engine from the details of the Z39.50 protocol and minimize the effort needed to interface the server to natural language search engines other than PRISE.
The Z39.50/PRISE software produced by NIST, an agency of the U.S. government, is by statute not subject to copyright in the United States. Recipients of this software assume all responsibilities associated with its operation, modification and maintenance.
PRISE SearchRelevance feedback is a technique for query enhancement for more effective search and retrieval. After performing a search and retrieving a set of documents, the user provides the information retrieval (IR) application with feedback by designating documents as good examples of the sort of information the user is searching for. The user can then ask the IR application to show suggested terms for addition to the query - terms derived from exemplary documents - and add them or not, before performing the next search. This cycle can be repeated.
