A method in linguistic approximate reasoning bases on Non-homogeneous hedge algebras.

Abstract

The method in linguistic reasoning which was introduced in [7,8], based on extended hedge algebras. This article is aimed to establish some new inference rules being applicable in linguistic reasoning to the case that fuzzy clauses contain "Not so". Its basis is non-homogeneous hedge algebras which have been investigated recently [9-12]. Thanks to the approach such as building the deductive system in classical logic, fuzzy deductive system and the consistency of the fuzzy knowledge base will be examinated. Tom tiit.
