Evaluation of Topic Modeling performance on the 20News dataset, measured using the diversity metric.

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 | Topic Modeling |
| Dataset (including any stated split) | 20News |
| Metric | Topic Diversity |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 8 of 8 |
| 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

- [Topic Diversity](<https://www.sota2.com/research/sota/topic-modeling-on-20news.md?metric=Topic%20Diversity>): Higher is better; unit: PERCENT.
