# Semantic Textual Similarity on MS-COCO CxC annotations 5k (test) Source: [Semantic Textual Similarity on MS-COCO CxC annotations 5k (test)]() Collection index: [llms.txt]() Data updated: 2026-02-26T06:04:37.932Z Evaluation of Semantic Textual Similarity performance using the 5k test split of the MS-COCO CxC annotations dataset, reporting Spearman's R correlation statistics. 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 | Semantic Textual Similarity | | Dataset (including any stated split) | MS-COCO CxC annotations 5k (test) | | Metric | Spearman's R (Avg) | | Unit | SCALAR | | Direction | Higher is better | | Results loaded | 11 of 11 | | 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 - [Spearman's R (Avg)](): Higher is better; unit: SCALAR. - [Spearman's R (Std Dev)](): Lower is better; unit: SCALAR. ## Recorded results | Method | Spearman's R (Avg) | Result date | Report paper | | --- | --- | --- | --- | | PromCSE | 0.74 | Not recorded | 68fa6da21e209131cea3b058 | | MURAL | 0.739 | Not recorded | 68fa6da21e209131cea3b058 | | PromCSE | 0.736 | Not recorded | 68fa6da21e209131cea3b058 | | SimCSE | 0.732 | Not recorded | 68fa6da21e209131cea3b058 | | SimCSE | 0.73 | Not recorded | 68fa6da21e209131cea3b058 | | ALIGN | 0.727 | Not recorded | 68fa6da21e209131cea3b058 | | PromCSE | 0.712 | Not recorded | 68fa6da21e209131cea3b058 | | DiffCSE | 0.701 | Not recorded | 68fa6da21e209131cea3b058 | | PromptBERT | 0.7 | Not recorded | 68fa6da21e209131cea3b058 | | SimCSE | 0.675 | Not recorded | 68fa6da21e209131cea3b058 | | GloVe embeddings (avg.) | 0.551 | Not recorded | 68fa6da21e209131cea3b058 | ### PromCSE Spearman's R (Avg): 0.74.
