# Part-of-Speech Tagging on Wall Street Journal (WSJ) section 23 (test) Source: [Part-of-Speech Tagging on Wall Street Journal (WSJ) section 23 (test)]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:27:33.572Z Evaluation of Part-of-Speech (POS) Tagging performance on the test split of Section 23 of the Wall Street Journal (WSJ) corpus, typically measured using Accuracy. 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 | Part-of-Speech Tagging | | Dataset (including any stated split) | Wall Street Journal (WSJ) section 23 (test) | | Metric | Accuracy | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 12 of 12 | | 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 - [Accuracy](): Higher is better; unit: PERCENT. ## Recorded results | Method | Accuracy | Result date | Report paper | | --- | --- | --- | --- | | BiLSTM-LAN | 97.65 | Not recorded | 68fa66981e209131cea11358 | | Yasunaga et al. | 97.58 | Not recorded | 68fa66981e209131cea11358 | | Xin et al. | 97.58 | Not recorded | 68fa66981e209131cea11358 | | Huang et al. | 97.55 | Not recorded | 68fa66981e209131cea11358 | | Ma and Hovy | 97.55 | Not recorded | 68fa66981e209131cea11358 | | Zhang et al. | 97.55 | Not recorded | 68fa66981e209131cea11358 | | Liu et al. | 97.53 | Not recorded | 68fa66981e209131cea11358 | | Yang et al. | 97.51 | Not recorded | 68fa66981e209131cea11358 | | BiLSTM-softmax | 97.51 | Not recorded | 68fa66981e209131cea11358 | | BiLSTM-CRF | 97.51 | Not recorded | 68fa66981e209131cea11358 | | Plank et al. | 97.22 | Not recorded | 68fa66981e209131cea11358 | | Transformer-softmax | 97.04 | Not recorded | 68fa66981e209131cea11358 | ### BiLSTM-LAN Accuracy: 97.65.
