# Overlapping Mention Recognition on ACE 2004 Source: [Overlapping Mention Recognition on ACE 2004]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:58:13.750Z Evaluation of Overlapping Mention Recognition performance on the ACE 2004 dataset, typically 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 | Overlapping Mention Recognition | | Dataset (including any stated split) | ACE 2004 | | Metric | Precision | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 16 of 16 | | 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](): Higher is better; unit: PERCENT. - [Recall](): Higher is better; unit: PERCENT. - [F1 Score](): Higher is better; unit: PERCENT. ## Recorded results | Method | Precision | Result date | Report paper | | --- | --- | --- | --- | | SH | 80.1 | Not recorded | 68fa64e51e209131cea0737c | | SH | 79.1 | Not recorded | 68fa64e51e209131cea0737c | | CRF (CASCADED) | 78.4 | Not recorded | 68fa64e51e209131cea0737c | | SH | 78 | Not recorded | 68fa64e51e209131cea0737c | | SH | 77.7 | Not recorded | 68fa64e51e209131cea0737c | | Semi-CRF | 76.1 | Not recorded | 68fa64e51e209131cea0737c | | Wang et al.
