Evaluation of Event Extraction performance on the ACE 2005 Event (ACE05 Evt) corpus, measured by Event Trigger F1 and Event Argument 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 | Event Extraction |
| Dataset (including any stated split) | ACE05 Evt |
| Metric | Event Trigger F1 |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 38 of 38 |
| 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

- [Event Trigger F1](<https://www.sota2.com/research/sota/event-extraction-on-ace05-evt.md?metric=Event%20Trigger%20F1>): Higher is better; unit: PERCENT.

- [Event Argument F1](<https://www.sota2.com/research/sota/event-extraction-on-ace05-evt.md?metric=Event%20Argument%20F1>): Higher is better; unit: PERCENT.
