Other Methods in Fuzzy Information Retrieval and Related Topics

Abstract

This chapter deals with methods in fuzzy retrieval that are not discussed in the last three chapters. To show that there is much room for further study in fuzzy retrieval, some problems are posed without a solution. Furthermore, digraph representation of bibliographic structure and a fuzzy database are discussed. Namely, 1. Functions for improving user interface in fuzzy retrieval are considered; problems of constructing layers on output of fuzzy retrieval and fuzzy profiles are studied. 2. Measures such as precision and recall are studied by using fuzzy sets. 3. A fuzzy relational database is briefly reviewed. 4. Studies in fuzzy information retrieval that have not been referred so far are reviewed. 5. An experimental system for fuzzy retrieval is outlined. 6. Studies of bibliographic structure using graphical representations are reviewed and application of fuzzy sets is considered.
