A Utility Theoretic Examination of the Probability Ranking Principle in Information Retrieval.
Gordon, Michael D.; Lenk, Peter
Journal of the American Society for Information Science, v42 n10 p703-14 Dec 1991
Discussion of probabilistic information retrieval (IR) systems challenges the probability ranking principle in IR from the perspective of (1) signal detection-decision theory and (2) utility theory. Calibration, certainty, and independent assessment are discussed in terms of the relevance of documents, and standard retrieval policies are analyzed. (nine references) (LRW)
