Query Expansion for Information Retrieval Support System Using Fuzzy Abductive Inference

Abstract

In recent years, we have been able to use very large scale databases through the Internet. However, user sometimes cannot retrieve information they need because of mismatching of words. Query expansion methods for information retrieval (IR) system have been studied. This paper proposes a new query expansion using fuzzy abductive inference for IR support system. The fuzzy abductive inference is the inference method based on Peng and Reggia's abductive inference. This method infers irredundant combinations of concept words for the query. Acquisition of relationships between concepts and terms is also studied in this paper.
