Definition
The application of fuzzy set theory to information retrieval (IR) is aimed at the definition of retrieval techniques capable of modeling, at least to some extent, the subjectivity, vagueness, and imprecision that is intrinsic to the process of locating information relevant to users’ needs. In the context of IR, fuzzy set theory has been applied to several purposes among which:
The definition of generalizations of the Boolean retrieval model and in particular the definition of flexible query languages to address the vagueness that may affect query formulation
The definition of flexible approaches to XML retrieval
The definition of flexible and personalized indexing algorithms
The definition of fuzzy thesauri and fuzzy clustering algorithms, which are often employed to extend the functionalities of a basic information retrieval system
The definition of flexible aggregation strategies of...
