An Information Retrieval Model Based on Modal Logic.
Nie, Jianyun
Information Processing and Management, v25 n5 p477-91 1989

A more general model is presented in which the basis for information retrieval is viewed as logical implication and the estimation of the correspondence between queries and documents is described in terms of modal logic.
