Yerkey, A. Neil – Journal of the American Society for Information Science, 1973
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 -…
