- Abstract
- The Cheshire II system was originally developed to provide a bridge from conventional online library catalogs to full-text online resources. Recently we have begun using the system to implement full-text and fielded searching of bibliographic information for the UC Berkeley Digital Library Initiative project sponsored by NSF, NASA and ARPA. The Cheshire system is also being used to provide scalable performance for image querying using the "Blobworld" image representation. This paper will review the characteristics of the Cheshire II system and examine its performance and behavior when applied to a collection of large full-text documents in the TREC Interactive Retrieval Track and its performance in Blobworld image searching

- Abstract
- Among the proposed innovations in the Clinton Administration's plans to develop a National Information Infrastructure is the creation of, and support for, digital or electronic libraries to store and provide access to the vast amounts of information expected to made available over the 'information superhighway'. Although the exact nature and future architecture of such libraries is still a matter for experimentation (and debate), there are several pioineering efforts underway to establish electronic libraries and to provide access to them. This paper describes one such effort underway at the University of California at Berkeley. In collaboration with four other universities we are developing interoperable electronic library servers containing the Computer Science technical reports for each participant and making them available over the Internet using standard protocols

- Abstract
- The Cheshire 2 project is developing a next generation online catalogue and full text information retrieval system using advanced information retrieval techniques. It is being deployed at the University of California Berkeley Astronomy-Mathematics-Statistics Library, USA, and its use and acceptance is being evaluated using transaction monitoring and questionnaires. Describes the system architecture and user evaluation tools

- Abstract
- This article presents the results of research into the automatic selection of Library of Congress Classification numbers based on the titles and subject headings in MARC records. The method used in this study was based on partial match retrieval techniques using various elements of new recors (i.e., those to be classified) as "queries", and a test database of classification clusters generated from previously classified MARC records. Sixty individual methods for automatic classification were tested on a set of 283 new records, using all combinations of four different partial match methods, five query types, and three representations of search terms. The results indicate that if the best method for a particular case can be determined, then up to 86% of the new records may be correctly classified. The single method with the best accuracy was able to select the correct classification for about 46% of the new records.
