Pirkola, Ari; Jarvelin, Kalervo
Journal of the American Society for Information Science and Technology, v52 n7 p575-83 May 2001
The resolution power of a key is its ability, in the context of other keys for a given request, to increase query performance. This article studies the statistical properties of search keys, methods of characterizing the resolution power of keys automatically, and effects keys of varying resolution power have on retrieval effectiveness.
