Evaluation of Open-Domain Question Answering performance on the Natural Questions (NQ) dataset, focusing on retrieval and ranking metrics (R@K, MRR).

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) | NQ |
| Metric | R@1 |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 4 of 4 |
| 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

- [R@1](<https://www.sota2.com/research/sota/open-domain-question-answering-on-nq-retrieval.md?metric=R%401>): Higher is better; unit: PERCENT.

- [R@10](<https://www.sota2.com/research/sota/open-domain-question-answering-on-nq-retrieval.md?metric=R%4010>): Higher is better; unit: PERCENT.

- [MRR@10](<https://www.sota2.com/research/sota/open-domain-question-answering-on-nq-retrieval.md?metric=MRR%4010>): Higher is better; unit: PERCENT.
