Evaluation of the lexical diversity of generated text using the PersonaChatGen dataset, measured via metrics including Dist-1, Dist-2, Ent-4, and Self-BLEU.

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 Diversity Analysis |
| Dataset (including any stated split) | PersonaChatGen |
| Metric | Dist-1 |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 1 of 1 |
| 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

- [Dist-1](<https://www.sota2.com/research/sota/lexical-diversity-analysis-on-personachatgen.md?metric=Dist-1>): Higher is better; unit: SCALAR.

- [Dist-2](<https://www.sota2.com/research/sota/lexical-diversity-analysis-on-personachatgen.md?metric=Dist-2>): Higher is better; unit: SCALAR.

- [Ent-4](<https://www.sota2.com/research/sota/lexical-diversity-analysis-on-personachatgen.md?metric=Ent-4>): Higher is better; unit: SCALAR.

- [Self-BLEU](<https://www.sota2.com/research/sota/lexical-diversity-analysis-on-personachatgen.md?metric=Self-BLEU>): Lower is better; unit: SCALAR.
