Evaluation of model performance on the test split of the LFQA dataset for Long-Form Question Answering, measured using R-L, METEOR, BERTSCORE, BLEURT-20, and MAUVE.

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 | Long-Form Question Answering |
| Dataset (including any stated split) | LFQA (test) |
| Metric | R-L |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 3 of 3 |
| 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

- [R-L](<https://www.sota2.com/research/sota/long-form-question-answering-on-lfqa-test.md?metric=R-L>): Higher is better; unit: PERCENT.

- [METEOR](<https://www.sota2.com/research/sota/long-form-question-answering-on-lfqa-test.md?metric=METEOR>): Higher is better; unit: PERCENT.

- [BERTSCORE](<https://www.sota2.com/research/sota/long-form-question-answering-on-lfqa-test.md?metric=BERTSCORE>): Higher is better; unit: PERCENT.

- [BLEURT-20](<https://www.sota2.com/research/sota/long-form-question-answering-on-lfqa-test.md?metric=BLEURT-20>): Higher is better; unit: PERCENT.

- [MAUVE](<https://www.sota2.com/research/sota/long-form-question-answering-on-lfqa-test.md?metric=MAUVE>): Higher is better; unit: PERCENT.
