This research aimed at the development of a system which supports a domain expert to discover objectively reliable and subjectively interesting rules in databases. We developed the modules to automatically estimate the reliability of rules, model the subjective interest of the domain expert, and balance the objective reliability and subjective interest, and then embedded the modules into the main body of the system. We also confirmed the effectiveness of each module through some simulations and experiments using real clinical datasets.
