Evaluation of Grammatical Error Correction performance on the development split of the UA-GEC+Fluency dataset, measured using Precision (P), Recall (R), and F0.5 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 | Grammatical Error Correction |
| Dataset (including any stated split) | UA-GEC+Fluency (dev) |
| Metric | Precision |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 7 of 7 |
| 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

- [Precision](<https://www.sota2.com/research/sota/grammatical-error-correction-on-ua-gec-plus-fluency-dev.md?metric=Precision>): Higher is better; unit: PERCENT.

- [Recall](<https://www.sota2.com/research/sota/grammatical-error-correction-on-ua-gec-plus-fluency-dev.md?metric=Recall>): Higher is better; unit: PERCENT.

- [F0.5 Score](<https://www.sota2.com/research/sota/grammatical-error-correction-on-ua-gec-plus-fluency-dev.md?metric=F0.5%20Score>): Higher is better; unit: PERCENT.
