Abstract

The research on expert systems has been a hotspot. In order to resolve the problems about knowledge acquisition in complete and incomplete knowledge representation systems, the algorithm of knowledge acquisition based on rough set theory is proposed. Let the knowledge representation system be a decision table, the useful knowledge can be obtained by simplification of the decision table. The algorithm of computation of condition attributes’ reductions and the algorithm of computation of reduction of decision rule are researched to simplify the decision table. When there are missing values in knowledge representation systems, the missing data should be completed by the algorithm of missing values’ completion firstly. This algorithm of knowledge acquisition based on rough set theory can obtain a minimal set of decision rules which can be used to reason in expert systems. The approach of knowledge acquisition can be used to simplify uncertain and incomplete knowledge representation systems.
