Evaluation of model faithfulness on the 800-sample subset of the tldr\_news dataset, measured using metrics such as BLEU, ROUGE-L, SentenceBert, PR, and KL divergence.

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 | Faithfulness Evaluation |
| Dataset (including any stated split) | tldr\_news 800 samples |
| Metric | BLEU |
| 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

- [BLEU](<https://www.sota2.com/research/sota/faithfulness-evaluation-on-tldr_news-800-samples.md?metric=BLEU>): Higher is better; unit: PERCENT.

- [ROUGE-L Precision](<https://www.sota2.com/research/sota/faithfulness-evaluation-on-tldr_news-800-samples.md?metric=ROUGE-L%20Precision>): Higher is better; unit: PERCENT.

- [ROUGE-L Recall](<https://www.sota2.com/research/sota/faithfulness-evaluation-on-tldr_news-800-samples.md?metric=ROUGE-L%20Recall>): Higher is better; unit: PERCENT.

- [ROUGE-L F1](<https://www.sota2.com/research/sota/faithfulness-evaluation-on-tldr_news-800-samples.md?metric=ROUGE-L%20F1>): Higher is better; unit: PERCENT.

- [SentenceBert Similarity](<https://www.sota2.com/research/sota/faithfulness-evaluation-on-tldr_news-800-samples.md?metric=SentenceBert%20Similarity>): Higher is better; unit: SCALAR.

- [PR Score](<https://www.sota2.com/research/sota/faithfulness-evaluation-on-tldr_news-800-samples.md?metric=PR%20Score>): Higher is better; unit: PERCENT.

- [KL Divergence](<https://www.sota2.com/research/sota/faithfulness-evaluation-on-tldr_news-800-samples.md?metric=KL%20Divergence>): Lower is better; unit: SCALAR.
