# Response Selection with No Correct Response (Subtask 2) on Ubuntu Track 2 DSTC 8 (test) Source: [Response Selection with No Correct Response (Subtask 2) on Ubuntu Track 2 DSTC 8 (test)]() Collection index: [llms.txt]() Data updated: 2026-02-26T06:01:21.343Z Evaluation of response selection performance on the test set of DSTC 8, Track 2, specifically focusing on the subtask where no ground truth response is provided (Subtask 2), measured using Recall@K and MRR. 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 | Response Selection with No Correct Response (Subtask 2) | | Dataset (including any stated split) | Ubuntu Track 2 DSTC 8 (test) | | Metric | Recall@1 | | 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 - [Recall@1](): Higher is better; unit: PERCENT. - [Recall@5](): Higher is better; unit: PERCENT. - [Recall@10](): Higher is better; unit: PERCENT. - [MRR](): Higher is better; unit: PERCENT. ## Recorded results | Method | Recall@1 | Result date | Report paper | | --- | --- | --- | --- | | Proposed Model | 50.6 | Not recorded | 68fa67501e209131cea1556b | ### Proposed Model Recall@1: 50.6. Result ID: 698d28748b517eb4331f6f49. [Reporting paper]() [Method origin paper]() Recorded evaluation configuration: {"Ensemble Size":"5","Mode":"Ensemble"}.
