Evaluation of model performance on the scarce subset of the Web Questions dataset for Open-Domain Question Answering, typically measured using Exact Match or 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 | Open-domain Question Answering |
| Dataset (including any stated split) | Web Questions (scarce) |
| Metric | Exact Match / F1 |
| Unit | PERCENT |
| 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

- [Exact Match / F1](<https://www.sota2.com/research/sota/open-domain-question-answering-on-web-questions-scarce.md?metric=Exact%20Match%20%2F%20F1>): Higher is better; unit: PERCENT.
