Evaluation of Conversational Discourse Parsing performance on the test split of the STAC dataset, reporting metrics such as Arc and Relation 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 | Conversational Discourse Parsing |
| Dataset (including any stated split) | STAC (test) |
| Metric | Arc Score |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 9 of 9 |
| 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

- [Arc Score](<https://www.sota2.com/research/sota/conversational-discourse-parsing-on-stac-test.md?metric=Arc%20Score>): Higher is better; unit: PERCENT.

- [Relation Score](<https://www.sota2.com/research/sota/conversational-discourse-parsing-on-stac-test.md?metric=Relation%20Score>): Higher is better; unit: PERCENT.

- [Link F1](<https://www.sota2.com/research/sota/conversational-discourse-parsing-on-stac-test.md?metric=Link%20F1>): Higher is better; unit: PERCENT.

- [Link+Rel F1](<https://www.sota2.com/research/sota/conversational-discourse-parsing-on-stac-test.md?metric=Link%2BRel%20F1>): Higher is better; unit: PERCENT.
