摘要
基于包含运算区分属性特征,通过对每个属性对应的对象集合进行包含和交运算来判断属性特征.利用包含、交运算判断了所有属性特征,得到了属性协调集和约简集,达到了概念格属性约简的目的.
Attribute characteristic was judged by include-operation and join-operation of object sets corresponding to every attribute based on using include-operation to distinguish attribute characteristic.Thereafter,all the attribute characteristics were found and correspondingly a consistent set and a reduce set of concept lattice were obtainedf,rom which the aim to reducing the attributes of concept lattice was reached.
