Evaluation of Open-domain Question Answering performance on the medium subset of the CuratedTREC dataset, typically measured using Exact Match and F1 score.

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 | Open-domain Question Answering |
| Dataset (including any stated split) | Curated TREC (medium) |
| Metric | EM/F1 Score |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 6 of 6 |
| 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

- [EM/F1 Score](<https://www.sota2.com/research/sota/open-domain-question-answering-on-curated-trec-medium.md?metric=EM%2FF1%20Score>): Higher is better; unit: PERCENT.
