Abstract

fetched live from OpenAlex

Answering queries using views has been the subject of numerous studies in database and information integration systems. In this work, we consider conjunctive queries with linear equality constraints. Such queries arise naturally in database applications, (heterogeneous) information integration, and in cooperative information systems. We propose a model for query answering in this context and introduce a corresponding rewriting algorithm that uses views to provide answers. We develop a prototype of this model in Java and describe its design and implementation details. This prototype provides a basis for us to further investigate important issues of data modeling and query processing in information integration systems.

Full frame distilled prediction

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.
