Models of Index Searching and Retrieval Effectiveness of Keyword-In-Context Indexes

Yerkey, A. Neil

Journal of the American Society for Information Science, 24, 4, 282-286, Jul-Aug 73

The retrieval effectiveness of Keywork-In-Context (KWIC) indexing is sought using a simple search simulation which constrains the user to approach a KWIC index with subject keywords and references dictated by a conventional index. A comparison of several KWIC index studies, using various methodologies, shows retrievability ratios of 35 percent - 70 percent. (6 references) (Author/SJ)
