Fuzzy sets in information retrieval: State of the art and research trends

Abstract

In this contribution some applications of Fuzzy Set Theory to Information Retrieval are described, as well as the more recent outcomes of this research field. Fuzzy Set Theory is applied to Information Retrieval to the main aim to define flexible systems, i.e. systems that can represent and manage the vagueness and subjectivity which characterizes the process of information representation and retrieval. © 2008 Springer-Verlag Berlin Heidelberg.
