Evaluation of Lexical Substitution performance on the test split of the CoInCo dataset, measured using metrics such as P@1, best, and OOT 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 | Lexical Substitution |
| Dataset (including any stated split) | CoInCo (test) |
| Metric | Best Score |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 4 of 4 |
| 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

- [Best Score](<https://www.sota2.com/research/sota/lexical-substitution-on-coinco-test.md?metric=Best%20Score>): Higher is better; unit: SCALAR.

- [Best Score (m)](<https://www.sota2.com/research/sota/lexical-substitution-on-coinco-test.md?metric=Best%20Score%20(m)>): Higher is better; unit: SCALAR.

- [OOT Score](<https://www.sota2.com/research/sota/lexical-substitution-on-coinco-test.md?metric=OOT%20Score>): Higher is better; unit: SCALAR.

- [OOT Score (m)](<https://www.sota2.com/research/sota/lexical-substitution-on-coinco-test.md?metric=OOT%20Score%20(m)>): Higher is better; unit: SCALAR.

- [P@1](<https://www.sota2.com/research/sota/lexical-substitution-on-coinco-test.md?metric=P%401>): Higher is better; unit: PERCENT.
