Berkeley's TREC 8 Interactive Track Entry: Cheshire II and Zprise

Abstract : This paper briefly discusses the UC Berkeley entry in the TREC 8 Interactive Track. In this year's study twelve searchers conducted six searches each, half on the Cheshire II system and the other half on the Zprise system, for a total of 72 searches. Questionnaires were administered to each participant to gather information about basic demographic and searching experience, about each search, about each of the systems, and finally, about the user's perceptions of the systems. In this paper, I will briefly describe the systems used in the study and how they differ in design goals and implementation. The results of the interactive track evaluations and the information derived from the questionnaires are then discussed and future improvements to the Cheshire II system are considered.
