A KNOWLEDGE-BASED METHOD FOR FUZZY QUERY PROCESSING FOR DOCUMENT RETRIEVAL
Shyi‐Ming Chen · Cybernetics & Systems · 1997
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 < a < b < c < d < 1. Intelligent retrieval capability and flexible user's queries are consequently provided for.
