This theory makes use of equivalence relations defined for each set of attributes in any table, and applies the concept like definability of a set, dependency among attributes, reduction of data, rule extraction, etc., to data analysis. In this paper, a problem of knowledge discovering in the form of rules from any table with non-deterministic information is discussed. At first, the rough sets based concept including rule extraction is surveyed, and this concept is extended to new one related to non-deterministic information. Then, a framework of rule extraction from tables with non-deterministic information is proposed, and some algorithms for handling such new concept are presented. Also implemented programs and a real execution of these programs are shown.}, pages = {13--28}, title = {On a Method to Extract Rules from a Table with Non-deterministic Information: A Rough Sets based Approach}, volume = {34}, year = {2002}, yomi = {サカイ, ヒロシ} }
