Evaluation of multi-hop question answering retrieval performance on the 2WikiMultihopQA dataset, measured using Precision@K (PR@5, PR@10) and overall QA Accuracy.

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 | Multi-hop QA Retrieval |
| Dataset (including any stated split) | 2WikiMultihopQA |
| Metric | PR@5 |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 8 of 8 |
| 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

- [PR@5](<https://www.sota2.com/research/sota/multi-hop-qa-retrieval-on-2wikimultihopqa.md?metric=PR%405>): Higher is better; unit: PERCENT.

- [PR@10](<https://www.sota2.com/research/sota/multi-hop-qa-retrieval-on-2wikimultihopqa.md?metric=PR%4010>): Higher is better; unit: PERCENT.

- [QA Accuracy](<https://www.sota2.com/research/sota/multi-hop-qa-retrieval-on-2wikimultihopqa.md?metric=QA%20Accuracy>): Higher is better; unit: PERCENT.
