Evaluation of model performance on the PaperPDF English 1.0 dataset for Long PDF Understanding, utilizing metrics such as ANLS, F1, Rouge, and GPT-Acc.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Long PDF Understanding |
| Dataset (including any stated split) | PaperPDF English 1.0 |
| Metric | ANLS |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 14 of 14 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [ANLS](<https://www.sota2.com/research/sota/long-pdf-understanding-on-paperpdf-english-1-0.md?metric=ANLS>): Higher is better; unit: SCALAR.

- [F1 Score](<https://www.sota2.com/research/sota/long-pdf-understanding-on-paperpdf-english-1-0.md?metric=F1%20Score>): Higher is better; unit: PERCENT.

- [Rouge Score](<https://www.sota2.com/research/sota/long-pdf-understanding-on-paperpdf-english-1-0.md?metric=Rouge%20Score>): Higher is better; unit: PERCENT.

- [GPT Accuracy](<https://www.sota2.com/research/sota/long-pdf-understanding-on-paperpdf-english-1-0.md?metric=GPT%20Accuracy>): Higher is better; unit: PERCENT.
