Evaluation of code-switched text synthesis performance on the test split of the SEAME Chinese-English dataset, measured using CS Rate, F, S, and Geo. Mean metrics.

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 | Code-switched text synthesis |
| Dataset (including any stated split) | SEAME Chinese-English (test) |
| Metric | CS Rate |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| 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

- [CS Rate](<https://www.sota2.com/research/sota/code-switched-text-synthesis-on-seame-chinese-english-test.md?metric=CS%20Rate>): Higher is better; unit: PERCENT.

- [F Score](<https://www.sota2.com/research/sota/code-switched-text-synthesis-on-seame-chinese-english-test.md?metric=F%20Score>): Higher is better; unit: SCALAR.

- [S Score](<https://www.sota2.com/research/sota/code-switched-text-synthesis-on-seame-chinese-english-test.md?metric=S%20Score>): Higher is better; unit: SCALAR.

- [Geometric Mean](<https://www.sota2.com/research/sota/code-switched-text-synthesis-on-seame-chinese-english-test.md?metric=Geometric%20Mean>): Higher is better; unit: SCALAR.
