Evaluation of Information Retrieval performance on the LoTTE dataset, reporting scores for specific components like Search and Forum pools.

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 | Information Retrieval |
| Dataset (including any stated split) | LoTTE |
| Metric | Search (pooled) Score |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 3 of 3 |
| 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

- [Search (pooled) Score](<https://www.sota2.com/research/sota/information-retrieval-on-lotte.md?metric=Search%20(pooled)%20Score>): Higher is better; unit: PERCENT.

- [Forum (pooled) Score](<https://www.sota2.com/research/sota/information-retrieval-on-lotte.md?metric=Forum%20(pooled)%20Score>): Higher is better; unit: PERCENT.
