Dataset Summary

The NLI4CT dataset introduces a challenging two-part benchmark designed to enable large-scale automated reasoning over full clinical trial reports (CTRs): (1) determining whether a natural language statement is entailed or contradicted by a CTR (textual entailment) and (2) retrieving the specific evidence sentences that justify that label. It covers 2,400 expert-annotated instances drawn from breast cancer trials, each mapped to one of four CTR sections—eligibility, intervention, results, or adverse events—and includes both single-trial and comparison scenarios.
