Fuzzy Data Mining of Term Associations for Flexible Query Answering
Category: Data Management
Tags: data
Overview This paper presents an approach to data mine a document base for term associations that are useful for query expansion in flexible query answering. Fuzzy logic and probability theory are applied to handle key aspects of uncertainty arising from vagueness of terms and randomness of term occurrence. In particular, the paper considers conditional probability to increase the utility of association, Chebyshev's inequality to reflect statistical confidence, and the relative cardinality measure, introduced by Delgado et al., to handle the vague concept of a set of documents characterized by a particular term.
