Evaluation of model performance on a 500-sample subset of the test split of the HotpotQA dataset for multi-hop question answering, reporting F1 and EM scores.

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 Question Answering |
| Dataset (including any stated split) | HotpotQA 500 samples (test) |
| Metric | F1 Score |
| 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

- [F1 Score](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-hotpotqa-500-samples-test.md?metric=F1%20Score>): Higher is better; unit: PERCENT.

- [Exact Match (EM)](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-hotpotqa-500-samples-test.md?metric=Exact%20Match%20(EM)>): Higher is better; unit: PERCENT.
