PyTorch impelementations of BERT-based Spelling Error Correction Models.

Overview

BertBasedCorrectionModels

基于BERT的文本纠错模型,使用PyTorch实现

数据准备

  1. http://nlp.ee.ncu.edu.tw/resource/csc.html下载SIGHAN数据集
  2. 解压上述数据集并将文件夹中所有 ''.sgml'' 文件复制至 datasets/csc/ 目录
  3. 复制 ''SIGHAN15_CSC_TestInput.txt'' 和 ''SIGHAN15_CSC_TestTruth.txt'' 至 datasets/csc/ 目录
  4. 下载 https://github.com/wdimmy/Automatic-Corpus-Generation/blob/master/corpus/train.sgml 至 datasets/csc 目录
  5. 请确保以下文件在 datasets/csc 中
    train.sgml
    B1_training.sgml
    C1_training.sgml  
    SIGHAN15_CSC_A2_Training.sgml  
    SIGHAN15_CSC_B2_Training.sgml  
    SIGHAN15_CSC_TestInput.txt
    SIGHAN15_CSC_TestTruth.txt
    

环境准备

  1. 使用已有编码环境或通过 conda create -n python=3.7 创建一个新环境(推荐)
  2. 克隆本项目并进入项目根目录
  3. 安装所需依赖 pip install -r requirements.txt
  4. 如果出现报错 GLIBC 版本过低的问题(GLIBC 的版本更迭容易出事故,不推荐更新),openCC 改为安装较低版本(例如 1.1.0)
  5. 在当前终端将此目录加入环境变量 export PYTHONPATH=.

训练

运行以下命令以训练模型,首次运行会自动处理数据。

python tools/train_csc.py --config_file csc/train_SoftMaskedBert.yml

可选择不同配置文件以训练不同模型,目前支持以下配置文件:

  • train_bert4csc.yml
  • train_macbert4csc.yml
  • train_SoftMaskedBert.yml

如有其他需求,可根据需要自行调整配置文件中的参数。

实验结果

SoftMaskedBert

component sentence level acc p r f
Detection 0.5045 0.8252 0.8416 0.8333

Bert类

MACBERT4CSC 0.9380 0.8736 0.9047

sentence level

MACBERT4CSC 0.8027 0.8525 0.7251 0.7836

推理

方法一,使用inference脚本:

python inference.py --ckpt_fn epoch=0-val_loss=0.03.ckpt --texts "我今天很高心"
# 或给出line by line格式的文本地址
python inference.py --ckpt_fn epoch=0-val_loss=0.03.ckpt --text_file /ml/data/text.txt

其中/ml/data/text.txt文本如下:

我今天很高心
你这个辣鸡模型只能做错别字纠正

方法二,直接调用

texts = ['今天我很高心', '测试', '继续测试']
model.predict(texts)

方法三、导出bert权重,使用transformers或pycorrector调用

  1. 使用convert_to_pure_state_dict.py导出bert权重
  2. 后续步骤参考https://github.com/shibing624/pycorrector/blob/master/pycorrector/macbert/README.md
