My research focuses in modeling data constraints and relationships using Integrity Rule languages, with special interest in automatically infering these rules directly from the raw data. My most recent work involves studying a very flexible Integrity Rule language named Denial Constraints, and researching ways to automatically discover them from the data, in addition to improving the quality of the Denial Constraints discovered by state-of-the-art algorithms. My contributions are owed to refining DC "quality" or "validity" metrics by taking into consideratin the statistical significance of the rules, ensuring resulting data rules always correspond to some intrinsic correspondence between the data attribute values.
