- An Evaluation of the Interactive Query Expansion in an Online Library Catalogue with a Graphical User Interface. Hancock-Beaulieu, Micheline And Others Computer Graphics Computer Interfaces Computer Software Evaluation Feedback Library Catalogs Online Searching Relevance (Information Retrieval) Search Strategies Users (Information) An online library catalog was used to evaluate an interactive query expansion facility based on relevance feedback for the Okapi, probabilistic, term weighting, retrieval system. A graphical user interface allowed searchers to select candidate terms extracted from relevant retrieved items to reformulate queries. Results suggested that the interactive query expansion was lower and retrieval performance was less effective. (Author/AEF)
