Abstract
We developed T oronto O pen D ata S earch to support the ad hoc , interactive discovery of connections or linkages between datasets. It can be used to efficiently navigate through the open data cloud. Our system consists of three parts: a user-interface provided by a Web application; a scalable backend infrastructure that supports navigational queries; and a dynamic repository of open data tables. Our system uses LSH Ensemble, an efficient index structure, to compute linkages (attributes in two datasets with high containment score) in real time at Internet scale. Our application allows users to navigate along these linkages by joining datasets. LSH Ensemble is scalable, providing millisecond response times for linkage discovery queries even over millions of datasets. Our system offers users a highly interactive experience making unrelated (and unlinked) dynamic collections of datasets appear as a richly connected cloud of data that can be navigated and combined easily in real time.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
