T5 for Chinese Spelling Correction Model
中文拼写纠错模型
shibing624/mengzi-t5-base-chinese-correction
evaluate SIGHAN2015 test data:
- Sentence Level: precision:0.8321, recall:0.6390, f1:0.7229
训练使用的数据集为下方提供的“SIGHAN+Wang271K中文纠错数据集”,在SIGHAN2015的测试集上达到接近SOTA水平。
未改动模型结构,finetune中文纠错数据集,评估纠错效果很好,模型潜力巨大。
Usage
本项目开源在中文文本纠错项目:pycorrector,可支持t5模型,通过如下命令调用:
pip install -U pycorrector
run:
from pycorrector.t5.t5_corrector import T5Corrector
nlp = T5Corrector("shibing624/mengzi-t5-base-chinese-correction").batch_t5_correct
i = "今天新情很好"
print(i, ' => ', nlp([i]))
output:
今天新情很好 => 今天心情很好 [('新', '心', 2, 3)]
