Papers with explicit benchmark + metric + eval mode fields.

Quality Controls

50.0%

1 papers report calibration/adjudication/IAA controls.

  • 2 papers explicitly name benchmark datasets in the sampled set.
  • 1 papers report at least one metric term in metadata extraction.
  • Start with the ranked shortlist below before reading all papers.

Primary action: Use this page to map benchmark mentions first; wait for stronger metric/QC coverage before strict comparisons.

Why This Matters (Expanded)

Why This Matters For Eval Research

  • 100% of papers report explicit human-feedback signals, led by pairwise preferences.
  • automatic metrics appears in 50% of papers in this hub.
  • LMSYS Chatbot Arena is a recurring benchmark anchor for cross-paper comparisons in this page.
Protocol Notes (Expanded)

Protocol Takeaways

  • Most common quality-control signal is rater calibration (50% of papers).
  • Rater context is mostly unspecified rater pools, and annotation is commonly pairwise annotation; use this to scope replication staffing.
  • Stratify by benchmark (LMSYS Chatbot Arena vs MT-Bench) before comparing methods.

Benchmark Interpretation

  • LMSYS Chatbot Arena appears in 100% of hub papers (2/2); use this cohort for benchmark-matched comparisons.
  • MT-Bench appears in 100% of hub papers (2/2); use this cohort for benchmark-matched comparisons.

Metric Interpretation

  • error rate is reported in 50% of hub papers (1/2); compare with a secondary metric before ranking methods.
