Frequently Asked Questions

What does the dataset contain?: Each record pairs a specific factual claim about a lease agreement with a related documentary excerpt. It includes an evidence sufficiency judgment, direct and complete support labels, notes on missing basis, and an assessment rationale.

A concise rationale explains the judgment. Users can sample records against the original agreements and their own requirements.
