In this paper, we present platform Coron, which is a domain independent, multi-purposed data mining platform, incorporating a rich collection of data mining algorithms. One of these algorithms is a multifunctional itemset mining algorithm called Zart, which is based on the Pascal algorithm, with some additional features. In particular, Zart is able to perform the following, usually independent, tasks: identify frequent closed itemsets and associate generators to their closures. This allows one to find minimal non-redundant association rules (as necessary and sufficient conditions). At present, Coron appears to be an original and working platform, integrating efficient algorithms for both itemset and association rule extraction, allowing a number of auxiliary operations for preparing and filtering data, and, for interpreting the extracted units of knowledge.
