On Symboloic Reasoning and Direct Interence Principle

Abstract

This paper discusses an approach using the M-valued symbolic logic with syllogistic reasoning and direct inference principle (reasoning from statistical information to conclusions about individuals), to manipu¬late statistical knowledge evaluated in a qualitative way. The graduation scale of M symbolic quantifiers is expressed in terms of truth degrees, which should not be arbitrary, but rather should be based on the available information from the knowledge base.
