In this article, we first summarize the more important aspects of a fuzzy logic relational database and show how a fuzzy relational database can be represented and handled using first-order logic. Given that the results obtained for fuzzy databases are satisfactory, we then tackle the problem of unc

β¦ Synopsis
A method of processing uncertain information in rule-based expert systems is presented. The method is based on the multiple-valued threshold logic and provides effective computer implementation owing to minimum requirements on arithmetic operations. The possibility of an adequately fine operation with uncertainty is guaranteed. The modelling of various schemes of human reasoning is allowed merely by altering the threshold values.

This article differentiates between the four main knowledge levels of a human expert: namely, structural conceptual heuristic, and epistemological knowledge. The conceptual relationships between these various types of knowledge are constituent elements of the deep knowledge encountered in industrial
This paper discusses the adaptation of basic knowledge representation constructs to the treatment of imprecise or uncertain information, the modelling of which uses distribution and scalar value respectively. Other representation issues such as the use of variables and the organization of rules in n
