Abstract

We present work in progress on a new methodology for leveraging the semantic content of ontologies to guide knowledge discovery in databases. Our system scans new databases to obtain type and constraint information, which users verify. Our system then uses this information in the context of a shared ontology to intelligently guide the potentially combinatorial process of feature construction. Further, our system learns each time it is applied, easing the user's verification task on subsequent runs..
