Association rules are the very valuable kind of law in data mining. The fitness of time is seldom illustrated by traditional association rules, which losses a number of useful implicit rules. On the basis of further study of other association rules mining algorithms, this paper has developed Apriori-extended mining periodic temporal association rules(More)
Concept lattice has many applications and isomorphic judgment of concept lattice is important in some fields. This paper presents a novel algorithm of complete lattice isomorphic judgment. The algorithm, first, introduces a layer computing method which divides the nodes into four types according to their indegree and outdegree. Then the equivalence classes(More)
