A Fuzzy Document Retrieval System for Ship Inspectors

Abstract

A great deal of notifications are circulated to ship inspectors from the head office. Those state papers are increased year by year. It is very troublesome and timeconsuming for them to keep and refer to a pile of notifications. A database and retrieval system which holds notifications in an electronic form is considered to be effective to help ship inspectors with their routine. In an usual database system, a record is retrieved only with keywords, but approximate or imprecise information stored in our natural databases is also helpful. By fuzzy queries which use fuzzy predicates based on the theory of fuzzy, it is possible to realize more precise and user-friendly document retrieval system than the conventional one. In this paper, a fuzzy document retrieval system for ship inspectors using fuzzy queries is investigated and implemented on a portable computer to show how effective and practical.
