High-Signal Coverage

100.0%

20 / 20 sampled papers are not low-signal flagged.

Replication-Ready Set

3

Papers with explicit benchmark + metric + eval mode fields.

Quality Controls

0.0%

0 papers report calibration/adjudication/IAA controls.

  • 6 papers explicitly name benchmark datasets in the sampled set.
  • 3 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

  • 15% of papers report explicit human-feedback signals, led by critique/edit feedback.
  • simulation environments appears in 25% of papers in this hub.
  • LongBench is a recurring benchmark anchor for cross-paper comparisons in this page.
Protocol Notes (Expanded)

Protocol Takeaways

  • 1 sampled papers report both human evaluation and LLM-as-judge, supporting direct agreement checks.
  • Quality-control reporting is sparse in this slice; prioritize papers with explicit calibration or adjudication steps.
  • Rater context is mostly domain experts, and annotation is commonly trajectory-level annotation; use this to scope replication staffing.

Benchmark Interpretation

  • LongBench appears in 50% of hub papers (10/20); use this cohort for benchmark-matched comparisons.
  • WebArena appears in 50% of hub papers (10/20); use this cohort for benchmark-matched comparisons.

Metric Interpretation

  • accuracy is reported in 20% of hub papers (4/20); compare with a secondary metric before ranking methods.
  • precision is reported in 20% of hub papers (4/20); compare with a secondary metric before ranking methods.

Checklist

  • Gap: Papers with explicit human feedback

    Coverage is a replication risk (15% vs 45% target).

  • Gap: Papers reporting quality controls

    Coverage is a replication risk (0% vs 30% target).

  • Strong: Papers naming benchmarks/datasets

    Coverage is strong (100% vs 35% target).

  • Strong: Papers naming evaluation metrics

    Coverage is strong (60% vs 35% target).

  • Gap: Papers with known rater population

    Coverage is a replication risk (5% vs 35% target).

  • Gap: Papers with known annotation unit

    Coverage is a replication risk (20% vs 35% target).

Strengths

  • Most papers provide measurable evaluation context (100% benchmarks, 60% metrics).
  • Contains both human-eval and LLM-as-judge protocols for head-to-head methodology comparison.
  • Agentic evaluation appears in 25% of papers.

Known Gaps

  • Only 0% of papers report quality controls; prioritize calibration/adjudication evidence.
  • Rater population is under-specified (5% coverage).
  • Annotation unit is under-specified (20% coverage).

Suggested Next Analyses

  • Compare papers that report both human_eval and llm_as_judge to quantify judge-human agreement drift.
  • Stratify by benchmark (LongBench vs WebArena) before comparing methods.
  • Track metric sensitivity by reporting both accuracy and precision.
