# Aspect-Opinion Pair Extraction on 15res (test) Source: [Aspect-Opinion Pair Extraction on 15res (test)]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:43:18.687Z Evaluation of Aspect-Opinion Pair Extraction performance on the test split of the 15res dataset, measured using Precision, Recall, and F1 scores. 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 | Aspect-Opinion Pair Extraction (Pair) | | Dataset (including any stated split) | 15res (test) | | Metric | F1 Score | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 13 of 13 | | 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 - [F1 Score](): Higher is better; unit: PERCENT. - [Precision](): Higher is better; unit: PERCENT. - [Recall](): Higher is better; unit: PERCENT. ## Recorded results | Method | F1 Score | Result date | Report paper | | --- | --- | --- | --- | | Dual-MRC | 74.5 | Not recorded | 68fa69ae1e209131cea23568 | | LOTN | 73.29 | Not recorded | 68fa69ae1e209131cea23568 | | IOG | 71.91 | Not recorded | 68fa69ae1e209131cea23568 | | Seq2Path | 71.84 | Not recorded | 68fa712c1e209131cea4fb8d | | BMRC | 68.6 | Not recorded | 68fa712c1e209131cea4fb8d | | GAS | 67.93 | Not recorded | 68fa712c1e209131cea4fb8d | | Dual-MRC | 64.97 | Not recorded | 68fa69ae1e209131cea23568 | | InstructABSA2 | 62.59 | Not recorded | 68fa712c1e209131cea4fb8d | | InstructABSA1 | 60.31 | Not recorded | 68fa712c1e209131cea4fb8d | | Li-unified-R | 56.85 | Not recorded | 68fa69ae1e209131cea23568 | | Peng-two-stage | 56.23 | Not recorded | 68fa69ae1e209131cea23568 | | CMLA | 44.6 | Not recorded | 68fa69ae1e209131cea23568 | | RINANTE | 35.4 | Not recorded | 68fa69ae1e209131cea23568 | ### Dual-MRC F1 Score: 74.5.
