Abstract: Heterogeneous formal context is a new type of fuzzification for formal concept analysis that works with heterogeneous values. The evidence theory is introduced for reasoning on heterogeneous formal contexts. The thought of D-S combination formula is applied to heterogeneous formal contexts for reasoning. Then, the synthesis steps is proposed, according to the steps, and the heterogeneous formal contexts is demonstrated by an example in practice.

Key words: the D-S combination formula, heterogeneous formal contexts, evidence reasoning
