E-Referencer: Transforming Boolean OPACs to Web Search Engines.
Khoo, Christopher S. G.; Poo, Danny C. C.; Toh, Teck-Kang; Hong, Glenn
E-Referencer is an expert intermediary system for searching library online public access catalogs (OPACs) on the World Wide Web. It is implemented as a proxy server that mediates the interaction between the user and Boolean OPACs. It transforms a Boolean OPAC into a retrieval system with many of the search capabilities of Web search engines. E-Referencer encapsulates some of the knowledge and searching expertise of experienced librarians. It processes the user's natural language query, maps the query words to Library of Congress subject headings, selects a suitable search strategy, and formulates an appropriate search statement to send to the library system. Based on the user's relevance feedback on the search results, it further selects a strategy for refining the search. (Author/MES)
