DT-miner, a system that integrates association rules in the exploration framework of dynamic taxonomies,is presented. Dynamic taxonomies are a general model for the user-centric systematic and guided exploration of complex information bases. The goal of DT-miner is two-fold: from the one side, it provides a highly interactive, user-centered environment for the exploration of significant association rules according to users'??interests. From the other side, exploration through dynamic taxonomies can significantly benefit from association rule metrics that improve user understanding of the information base and can inform the selections he makes.
