Abstract: The concept lattice is an effective tool for knowledge discovering and knowledge processing, which has been successfully applied in many fields. However, lattice constructions with reduction operation are mostly based on minimum support and degree of confidence. At the same time, the degree of confidence is used to extract rules. This paper proposes the Hasse diagram with strong association which is constructed by the mutual information of information theory, and extracts rules by mutual information.

Key words: strong association rules, concept lattice, mutual information, rule extraction, data mining
