Knowledge reduction in formal fuzzy contexts

作者：

Highlights：

• We proposed a general method of knowledge reduction in formal fuzzy contexts.

• We gave some judging methods of attribute characteristics in fomal fuzzy contexts.

• We constucted the discernibility functions to calculating the attribute reducts.
