Bibliographic Coupling Bibliographies Computer Programs Cost Effectiveness Databases Indexing Information Retrieval Information Systems Library Automation Online Systems Relevance (Information Retrieval) Search Strategies Thesauri Vocabulary Two programs addressed the development of information retrieval systems useful to a variety of users. One program was designed to examine aspects of indexing and information display. Experiments with different indexing and display systems revealed that for good relevance judgements, a display with full citation, keyboards, and abstract is necessary. However, the cost of searching abstracts is high, and adequate retrieval can be made using titles and keyboards. The second program was undertaken to improve computer-search quality and efficiency for large bibliographic files. An algorithm was generated whereby citations are clustered for presentation to the user. Preliminary findings indicated that a term map is required which would project found vocabulary up the hierarchy toward greater generality. (CH) |
