## What this evaluates

Evaluates the quality, comprehensiveness, and evidence support of AI-generated academic peer reviews across multiple dimensions. It also measures the alignment between AI-identified research limitations and human reviewer findings, as well as the impact of citation time spans on review coherence and technical focus.

## Datasets

- **EchoReview-Bench** — total ?; splits: test_a (-1), test_b (233)

## Metrics

- `Overall Quality score` **(primary)** — range: [0, 10]
  - Mean of scores (0-10) across Comprehensiveness, Specificity, Evidence Support, and Consistency. Each review is scored three times by an LLM judge at temperature 0.1, and the average is taken as the final score.
- `Overlap Ratio` — range: [0, 1]
  - R_overlap = |H ∩ E^(M)| / |H ∪ E^(M)|, where H is the set of research issues identified by humans and E^(M) is the set identified by model M. Macro-averaged across papers.
- `Human-only Ratio` — range: [0, 1]
  - R_human-only = |H \ O^(M)| / |H|, measuring the proportion of human-identified issues missed by the model. Macro-averaged across papers.
- `Model-only Ratio` — range: [0, 1]
  - R_model-only = |E^(M) \ O^(M)| / |E^(M)|, measuring the proportion of model-identified issues not found by humans. Macro-averaged across papers.

## Input / output format

**Input**: Full text of the academic paper to be reviewed.

**Output**: Structured peer review report containing scores (0-10) and textual explanations for Comprehensiveness, Specificity, Evidence Support, and Consistency.

## Scoring recipe

```python
def compute_metrics(predictions, gold):
    # LLM-as-Judge scoring (Sec 3.1)
    scores = []
    for _ in range(3):
        dim_scores = llm_judge.predict(predictions, temp=0.1)
        scores.append(mean(dim_scores))
    overall_quality = mean(scores)

    # Ratio metrics (Sec 3.2)
    overlap_ratios, human_only_ratios, model_only_ratios = [], [], []
    for paper in papers:
        H = gold[paper].issues
        E = predictions[paper].issues
        O = H.intersection(E)
        overlap_ratios.append(len(O) / len(H.union(E)))
        human_only_ratios.append(len(H - O) / len(H))
        model_only_ratios.append(len(E - O) / len(E))
    return overall_quality, mean(overlap_ratios), mean(human_only_ratios), mean(model_only_ratios)
```

## Common pitfalls

- LLM-as-Judge scores are sensitive to temperature and prompt phrasing; the protocol strictly uses temp=0.1 and averages three independent runs.
- Weakness matching relies on GPT-5.2 to map surface-level statements to 'underlying research issues' via binary decisions, which may introduce semantic drift or over/under-matching.
- Pairwise win rates (Sec 3.3) require randomizing the presentation order of reviews to mitigate positional bias before feeding them to the judge LLM.

## Evidence (verbatim from paper)

> The judge model assigns a score from 0 to 10 for each dimension and computes the mean across all four dimensions as the Overall Quality score. To enhance evaluation stability and robustness, each review is independently scored three times under a temperature of 0.1, and the average is taken as the final score.
