Evaluation of model performance on the HotPotQA dataset for multi-hop question answering, reporting Task Score and Brier 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 | Multi-hop Question Answering |
| Dataset (including any stated split) | HotPotQA |
| Metric | Task Score |
| Unit | SCALAR |
| 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

- [Task Score](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-hotpotqa-task-score-brier.md?metric=Task%20Score>): Higher is better; unit: SCALAR.

- [Brier Score](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-hotpotqa-task-score-brier.md?metric=Brier%20Score>): Lower is better; unit: SCALAR.
