Evaluation of Question Answering Retrieval performance on the STaRK human-generated dataset, measured using Hit@1, Hit@5, and 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 | Question Answering Retrieval |
| Dataset (including any stated split) | STaRK human-generated |
| Metric | Hit@1 |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 9 of 9 |
| 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

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

- [Hit@5](<https://www.sota2.com/research/sota/question-answering-retrieval-on-stark-human-generated.md?metric=Hit%405>): Higher is better; unit: PERCENT.

- [MRR](<https://www.sota2.com/research/sota/question-answering-retrieval-on-stark-human-generated.md?metric=MRR>): Higher is better; unit: PERCENT.
