Evaluation of Part-of-Speech (POS) Tagging performance on the test split of the Lassy UD dataset, reporting accuracy.

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 | Part-of-speech Tagging |
| Dataset (including any stated split) | Lassy UD (test) |
| Metric | Accuracy |
| 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

- [Accuracy](<https://www.sota2.com/research/sota/part-of-speech-tagging-on-lassy-ud-test.md?metric=Accuracy>): Higher is better; unit: PERCENT.

- [Accuracy 95% CI](<https://www.sota2.com/research/sota/part-of-speech-tagging-on-lassy-ud-test.md?metric=Accuracy%2095%25%20CI>): Higher is better; unit: OTHER.
