Generally, in real Decision Information System (DIS), attributes' values of objects are continuous numerical. Numerical values are too fine to directly obtain knowledge or decision rules which are expressed by natural language. In this paper, based on membership functions of fuzzy linguistic, extracting linguistic decision rules from DIS is discussed. In(More)
As a rule, in real Decision Information System (DIS), attributes' values of objects are continuous numerical. And it is difficult to “read” good information from the data. Numerical values are too fine to directly obtain decision rules which are expressed by natural language. In this paper, based on genetic algorithms (GA), extracting(More)
