Abstract

fetched live from OpenAlex

Integrity constraints are the primary tool used to capture business rules and domain constraints in data management systems. When these constraints are not strictly enforced, poor data quality often arises, as inconsistencies occur between the data and the set of constraints. To resolve these inconsistencies, organisations often implement specific, sometimes manual, cleansing routines to fix the errors. As modern systems are expected to handle increasing amounts of highly heterogeneous data, often in dynamic data environments where the data and the constraints may change, manual cleansing routines are insufficient to handle this increased scale and heterogeneity. In this work, we present a set of new constraint repair operations that can be incorporated into a data quality tool that provides automated support for both data and constraint repair and management. Our holistic approach is designed to facilitate the curation and maintenance of both the data and the constraints. We focus on discovering trends, contextual information, and data patterns to understand how a business rule (constraint) has evolved. We also investigate how to find a minimal set of constraints that contain non-redundant information since enforcing extraneous constraints is costly and can negatively affect system performance. We conduct two case studies using real business datasets that demonstrate the quality and usefulness of our techniques.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
