Evaluation of Joint Entity and Relation Extraction performance on the test split of the WebNLG dataset, specifically using the 'last word annotation' subset, measured using Precision, Recall, and 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 | Joint Entity and Relation Extraction |
| Dataset (including any stated split) | WebNLG last word annotation (test) |
| Metric | Precision |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 8 of 8 |
| 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/joint-entity-and-relation-extraction-on-webnlg-last-word-annotation-test.md?metric=Precision>): Higher is better; unit: SCALAR.

- [Recall](<https://www.sota2.com/research/sota/joint-entity-and-relation-extraction-on-webnlg-last-word-annotation-test.md?metric=Recall>): Higher is better; unit: SCALAR.

- [F1 Score](<https://www.sota2.com/research/sota/joint-entity-and-relation-extraction-on-webnlg-last-word-annotation-test.md?metric=F1%20Score>): Higher is better; unit: SCALAR.
