Coron is a domain and platform independent, multi-purposed data mining toolkit, which incorporates not only a rich collection of data mining algorithms, but also allows a number of auxiliary operations. To the best of our knowledge, a data mining toolkit designed specifically for itemset extraction and association rule generation like Coron does not exist elsewhere. Coron also provides support for preparing and filtering data, and for interpreting the extracted units of knowledge.
In our case, the extracted knowledge units are mainly association rules. At the present time, finding association rules is one of the most important tasks in data mining. Association rules allow one to reveal "hidden" relationships in a dataset. Finding association rules requires first the extraction of frequent itemsets.
The system was developed at LORIA/INRIA Laboratory, France and is freely available at
