CIPHER Cross-Record Inference - FIR (Chain-of-Thought): leaderboard
Cross-record inference over privacy-hardened police First Information Reports whose narratives were masked with typed placeholders, from CIPHER (Roy Chowdhury et al., 2026): expert-validated questions combine structured fields with free-text narratives across 39 to 42 supplied records, answered with chain-of-thought prompting. Harmonic answer score in percent, the per-question harmonic mean of token overlap and Gemini 2.5 Flash acceptance; higher is better.
Metric: Harmonic answer score (%; per question the harmonic mean of token overlap with the reference and Gemini 2.5 Flash semantic acceptance, zero when rejected, averaged; First Information Reports (Indian police records) with typed placeholders from post-hoc masking; the full support-controlled context of 39-42 records including distractors; chain-of-thought prompting; greedy decoding).
