Dataset

三甲医院肺结节数据集,20000+字,BIO格式,形如:

中	B-ORG
共	I-ORG
中	I-ORG
央	I-ORG
致	O
中	B-ORG
国	I-ORG
致	I-ORG
公	I-ORG
党	I-ORG
十	I-ORG
一	I-ORG
大	I-ORG
的	O
贺	O
词	O

ATTENTION: 在处理自己数据集的时候需要注意:

  • 字与标签之间用空格("\ ")隔开
  • 其中句子与句子之间使用空行隔开

Steps

  1. 替换数据集
  2. 修改NER/train.py中的maxlen(超过截断,少于填充,最好设置训练集、测试集中最长句子作为MAX_SEQ_LEN)
  3. 下载权重,放到项目中
  4. 修改path.py中的地址
  5. 根据需要修改NER/train.py模型结构
  6. 训练前debug看下train_generator数据
  7. 训练
