Evaluation of model performance on the 50% coverage subset of the SQuAD 2.0 dataset for Extractive Question Answering, reporting F1 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 | Extractive Question Answering |
| Dataset (including any stated split) | SQuAD2 50% coverage |
| Metric | F1 Score |
| 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

- [F1 Score](<https://www.sota2.com/research/sota/extractive-question-answering-on-squad2-50-percent-coverage.md?metric=F1%20Score>): Higher is better; unit: PERCENT.
