Evaluation of Dialogue Thread Reconstruction performance on the test split of the DSTC 8 Track 2 dataset, focusing on Subtask 4, measured using clustering/coherence metrics like Precision, Recall, F-score, VI, Rand, and AMI.

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 | Dialogue Thread Reconstruction (Subtask 4) |
| Dataset (including any stated split) | Ubuntu Track 2 DSTC 8 (test) |
| Metric | Precision |
| Unit | PERCENT |
| 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

- [Precision](<https://www.sota2.com/research/sota/dialogue-thread-reconstruction-subtask-4-on-ubuntu-track-2-dstc-8-test.md?metric=Precision>): Higher is better; unit: PERCENT.

- [Recall](<https://www.sota2.com/research/sota/dialogue-thread-reconstruction-subtask-4-on-ubuntu-track-2-dstc-8-test.md?metric=Recall>): Higher is better; unit: PERCENT.

- [F-score](<https://www.sota2.com/research/sota/dialogue-thread-reconstruction-subtask-4-on-ubuntu-track-2-dstc-8-test.md?metric=F-score>): Higher is better; unit: PERCENT.

- [VI](<https://www.sota2.com/research/sota/dialogue-thread-reconstruction-subtask-4-on-ubuntu-track-2-dstc-8-test.md?metric=VI>): Higher is better; unit: PERCENT.

- [Rand](<https://www.sota2.com/research/sota/dialogue-thread-reconstruction-subtask-4-on-ubuntu-track-2-dstc-8-test.md?metric=Rand>): Higher is better; unit: PERCENT.

- [AMI](<https://www.sota2.com/research/sota/dialogue-thread-reconstruction-subtask-4-on-ubuntu-track-2-dstc-8-test.md?metric=AMI>): Higher is better; unit: PERCENT.
