A knowledge-based method for fuzzy query processing for document retrieval

Abstract

This paper presents a knowledge-based method for processing fuzzy queries and weighted-fuzzy, queries for document retrieval, where fuzzy concept matrices are used for knowledge representation and the elements in a fuzzy concept matrix are represented by trapezoidal fuzzy numbers parameterized by quadruples (a,b,c,d), where 0 less than or equal to a less than or equal to b less than or equal to c less than or equal to d less than or equal to 1. Intelligent retrieval capability and flexible user's queries are consequently provided for.
