Evaluation of Global Question Answering performance on the UltraDomain Legal dataset, measured by Comprehensiveness, Diversity, Empowerment, and Overall 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 | Global Question Answering |
| Dataset (including any stated split) | UltraDomain Legal |
| Metric | Comprehensiveness |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 6 of 6 |
| 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

- [Comprehensiveness](<https://www.sota2.com/research/sota/global-question-answering-on-ultradomain-legal.md?metric=Comprehensiveness>): Higher is better; unit: SCALAR.

- [Diversity](<https://www.sota2.com/research/sota/global-question-answering-on-ultradomain-legal.md?metric=Diversity>): Higher is better; unit: SCALAR.

- [Empowerment](<https://www.sota2.com/research/sota/global-question-answering-on-ultradomain-legal.md?metric=Empowerment>): Higher is better; unit: SCALAR.

- [Overall Score](<https://www.sota2.com/research/sota/global-question-answering-on-ultradomain-legal.md?metric=Overall%20Score>): Higher is better; unit: SCALAR.
