And Others Databases Electronic Equipment Information Retrieval Information Systems Input Output Devices Library Research Online Systems Relevance (Information Retrieval) Search Strategies Thesauri Use Studies In order to identify and explain the reasons for differences in average on-line search rates among terminal installations, the operations and performance of several facilities using the Lockheed DIALOG system for on-line searching of the ERIC data base were studied. Detailed examinations were made of such aspects as the DIALOG system response time as a function of the time of day or day of the week; the search commands and logic used by each of the terminal installations for their operations; the mix of complex, medium, or simple questions processed at each terminal location; and the extent and impact of the variant forms of descriptors in the file (e.g., singular and plural forms of the same term). Timing studies were performed to suggest some terminal procedures that could increase average on-line search speeds. Guidelines for searchers to consider for pre-search and terminal activities are presented at the end of the study. (Author/PF) |
