A Combination of Expert Opinion Approach to Probabilistic Information Retrieval, Part 1: The Conceptual Model [and] Part 2: Mathematical Treatment of CEO Model 3.

Thompson, Paul

Information Processing and Management, v26 n3 p371-94 1990

These two articles introduce a new model of probablistic information retrieval (PIR) that is based on the statistical technique of the combination of expert opinion (CEO), which in this model is the opinions of indexers and users. Part 1 presents the conceptual basis, while Part 2 explains the mathematical details. (73 references) (LRW)
