ONWSIB Deep-Dive Method Note

This appendix explains the short local follow-up pass used for the ONWSIB archive after the 2020-2026 scrape was reconciled.

Scope

  • Dataset: 463 ONWSIB decisions from 2020-2026
  • Coverage check: local counts matched observed CanLII browse counts for each year in scope
  • Source files: local JSON outputs in data/tribunal-decisions/

What The Deep-Dive Did

  • Ran in sidecar mode against local files only
  • Made no additional API calls
  • Applied rule-based outcome detection to the reconciled archive
  • Used predMinConfidence = 0.55 to keep the threshold conservative

Result

  • 12 high-confidence outcome reads in the current archive
  • 6 additional cases queued for manual review
  • Year-level gains came from 2022 (+2) and 2023 (+1); other years held steady

Year Summary

What This Note Does Not Claim

  • It does not create an official ONWSIB success rate.
  • It does not replace manual reading of difficult files.
  • It does not change the core public-record limitation: most ONWSIB outcomes remain unresolved in published materials.

Primary Files

Use this note as a methodology appendix for ONWSIB-only content. For worker-facing posts, the safest summary remains: the archive is reconciled, the deep-dive is local-only, and public outcome completeness is still limited.
