You are here: Cheshire II Home > Overview
The Cheshire II project is developing a next-generation online catalog and full-text information retrieval system using advanced IR techniques. This system is being deployed in a working library environment and its use and acceptance by local library patrons and remote network users are being evaluated. The Cheshire II system was designed to overcome twin problems of topical searching in online catalogs, search failure and information overload as well as to provide a bridge between the purely bibliographic realm of previous generations of online catalogs and the rapidly expanding realm of full-text and multimedia information resources. The system incorporates a client/server architecture with implementations of current information retrieval standards including Z39.50 and SGML and XML.
II system includes the following design features:
These design elements of the Cheshire II system represent a significant advance over the simple left-to-right matching of subject headings used in first generation online catalogs, and the Boolean keyword matching used in second generation online catalogs. The Cheshire II system was designed to be a next- or third generation online catalog using advanced information retrieval techniques to improve subject searching performance, help combat the twin problems of search failure and information overload, and to support networked access to global information resources using standardized information retrieval protocols.
