Abstract

fetched live from OpenAlex

Data in this table was used to conduct analyses for a paper titled, "Ontario's Pedestrian Crash Causation Study: A Focus on the Impact of Large-Scale Trends on Road Safety". The study examines large-scale trends that may have had an impact on pedestrian fatalities in Ontario, utilizing Ontario (Canada) collision data for the 15-year period, 2002 to 2016. Authors were Sarah C. Plonka, Sara Volo, Patrick A. Byrne, Ian Sinclair and Thadsha Prabha, of the Ontario Ministry of Transportation. Published in the Transportation Research Record.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
