Ax : Searching for Database Regularities Using Concept Networks

In many organizations, both business and scientific, we collect ever increasing amountsof data using information technology. Indeed, the technology for collecting data hasoutpaced our ability to analyze and interpret these very large databases. In this paper,we discuss the interaction of heuristic search and domain knowledge in the AXknowledge discovery tool. The search process rests on the use of rule quality measuresand the organization of domain knowledge. A small loan application database fromthe machine learning repository is used to illustrate the process
