Entry Vocabulary, Intermediaries, and Retrieval Performance.
Proceedings of the ASIST Annual Meeting, v38 p112-17 2001
When systems of ordering, such as classifications and thesauri, are used, two mappings are involved: objects (documents) in the collection and searchers' queries. Four means to achieve this are: relative indexes; syndetic structures; entry vocabulary indexes; and human intermediaries. These forms can supplement and augment each other. The conventional approach to retrieval performance evaluation, using relevance, precision, and recall can be used to evaluate performance of intermediaries. (AEF)
