Model of an intellectual search engine represented by the fuzzy sets theory

In this report an attempt to explain the role and place of the fuzzy set theory with its typical techniques and methods in the process of the knowledge representation is proffered. A usage of the fuzzy sets and fuzzy logic for organizing a knowledge base is described. Their role with their typical characteristics in the process of designing a system for searching and classifying documents based on knowledge is examined. A generalized model of an intellectual system for searching and classifying documents in the Web is proposed.
