Research into both the algorithmic and human approaches to information retrieval is required to improve information retrieval system design and database searching effectiveness. This study uses the human approach to examine the sources and effectiveness of search terms selected during mediated interactive information retrieval. The study focuses on determining the retrieval effectiveness of search terms identified by users and intermediaries from retrieved items during term relevance feedback.

Implications for the design and testing of automatic relevance feedback techniques that place greater emphasis on these sources and the practice of database searching are also discussed. A version of this paper was first presented at the ACM SIGIR conference in Dublin (Spink, 1994) .
