Abstract | Discusses the problems caused for both users and systems by queries containing negation, and presents an algorithm for transforming Boolean queries with negated terms into queries without negation using a hierarchical thesaurus. A set of user requests submitted to an academic library are also examined to determine the pattern and frequency of use of negation. (32 references) (CLB) |
