ABSTRACT
The use of logic in information retrieval (IR) models is examined through a bibliographic survey of the production in the field and critical analysis of relevant works. The survey reveals a growing volume of research on non-classical models that incorporate uncertainty, especially fuzzy logic in IR systems. The evolution of systems based on non-classical logics emerged from the classical/Boolean logic is discussed. It concludes with an attempt to respond to criticisms against logical formalism and recognizes the technical and conceptual evolution represented by the introduction of non-classical logical models in the field of IR.
