Evaluation of Passage Ranking performance on the TREC DL 2019 dataset, focusing on Mean Reciprocal Rank (MRR) and Recall at 1 (R@1).

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 | Passage Ranking |
| Dataset (including any stated split) | TREC DL 19 |
| Metric | MRR |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| 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

- [MRR](<https://www.sota2.com/research/sota/passage-ranking-on-trec-dl-2019-mrr-r-at-1.md?metric=MRR>): Higher is better; unit: PERCENT.

- [R@1](<https://www.sota2.com/research/sota/passage-ranking-on-trec-dl-2019-mrr-r-at-1.md?metric=R%401>): Higher is better; unit: PERCENT.
