A Task-Oriented Approach to Retrieval System Evaluation.

Hersh, William R.; And Others

Proceedings of the ASIS Annual Meeting, v32 p112-17 1995

Describes a task-oriented assessment of two MEDLINE searching systems by medical students, one using Boolean searching on human-indexed thesaurus terms and one using natural language searching on words in the title, abstract, and indexing terms. Highlights include user certainty in answering questions, time needed, and user satisfaction. (Author/LRW)
