Title:A study of the measurement of human performance

Abstract:This paper reports on an attempt to measure the performance of users of interactive information retrieval systems. The subjects studied were end users of the information who were doing their own interactive searches. The measures consist of a set of computerized diagnostic procedures applied to the sequences of commands used in querying the database. These diagnostics trigger various kinds of messages to the user. Presumably, the frequency with which a diagnostic is triggered is an index of the difficulties which the user may be having in doing a search. Although the utility to the user of the information retrieved is assumed to be the best overall measure of search outcome, it is the manner of using the system, not the search outcome, which is the focus of this report.
