Why This Matters For Eval Research

  • 100% of papers report explicit human-feedback signals, led by pairwise preferences.
  • automatic metrics appears in 35.2% of papers in this hub.
  • LMSYS Chatbot Arena is a recurring benchmark anchor for cross-paper comparisons in this page.

Protocol Takeaways

  • Most common quality-control signal is inter-annotator agreement reporting (2.4% of papers).
  • Rater context is mostly domain experts, and annotation is commonly pairwise annotation; use this to scope replication staffing.
  • Compare papers that report both human_eval and llm_as_judge to quantify judge-human agreement drift.

Benchmark Interpretation

  • LMSYS Chatbot Arena appears in 3.5% of hub papers (10/287); use this cohort for benchmark-matched comparisons.
  • AlpacaEval appears in 2.4% of hub papers (7/287); use this cohort for benchmark-matched comparisons.

Metric Interpretation

  • accuracy is reported in 16% of hub papers (46/287); compare with a secondary metric before ranking methods.
  • cost is reported in 7% of hub papers (20/287); compare with a secondary metric before ranking methods.
