| Abstract: | This paper puts forward approaches to attribute reduction and rules extraction in decision formal context.For that,different kinds of attributes which play different roles during attribute reduction are distinguished.Characters and judgement theorems of necessary attributes and unnecessary attributes are given.And then approaches to attribute reduction and rules extraction in decision formal context are obtained.Finally,a real example is used to demonstrate both its feasibility and effectiveness. |
