# Aspect-Opinion Pair Extraction on 14res (test) Source: [Aspect-Opinion Pair Extraction on 14res (test)]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:43:18.657Z Evaluation of Aspect-Opinion Pair Extraction performance on the test split of the 14res 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) | 14res (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 | 83.73 | Not recorded | 68fa69ae1e209131cea23568 | | LOTN | 82.21 | Not recorded | 68fa69ae1e209131cea23568 | | IOG | 80.23 | Not recorded | 68fa69ae1e209131cea23568 | | Seq2Path | 77.35 | Not recorded | 68fa712c1e209131cea4fb8d | | BMRC | 76.23 | Not recorded | 68fa712c1e209131cea4fb8d | | GAS | 75.15 | Not recorded | 68fa712c1e209131cea4fb8d | | Dual-MRC | 74.93 | Not recorded | 68fa69ae1e209131cea23568 | | InstructABSA2 | 71.37 | Not recorded | 68fa712c1e209131cea4fb8d | | InstructABSA1 | 70.46 | Not recorded | 68fa712c1e209131cea4fb8d | | Peng-two-stage | 56.1 | Not recorded | 68fa69ae1e209131cea23568 | | Li-unified-R | 55.34 | Not recorded | 68fa69ae1e209131cea23568 | | CMLA | 48.95 | Not recorded | 68fa69ae1e209131cea23568 | | RINANTE | 46.29 | Not recorded | 68fa69ae1e209131cea23568 | ### Dual-MRC F1 Score: 83.73.
