工具分享: 中文实体标注工具

发现了一款比较方便标注的工具https://github.com/jiesutd/SUTDAnnotator ，使用python2编写的界面，相对比较轻量，适合个人使用。但如果是团体使用的，还是web界面的会比较好。

 

运行Annotator_backup.py得到如下界面：open导入文件,选中要标注的词语，按下已设定好的快捷键A-V，即可完成对应的标注

            

 修改添加上自己所需的实体名：在对应的快捷键的右边输入实体名，按下remap按钮即可重新分配快捷键对应的实体名

 导出结果：export

                    

                    

 

 

其他更详细的操作参照github中的描述

 

将标注好的ann文件转成常用的训练样本的格式，以下有python3实现

 

 

import re

# txt2ner_train_data turn label str into ner trainable data
# s :labeled str  eg.'我来到[@1999年#YEAR*]的[@上海#LOC*]的[@东华大学#SCHOOL*]'

    result_2 = re.finditer(r'*]', s)
    begin = []
    end = []
    for each in result_1:
        begin.append(each.start())
    for each in result_2:

    i = 0
    j = 0
    while i < len(s):
        if i not in begin:
            ner_data.append([s[i], 0])
            i = i + 1
        else:

            entity, ner = ann.rsplit('#')

                    ner_data.append([entity[-1], 'E-' + ner])

            i = end[j]
            j = j + 1

    f = open(save_path, 'w', encoding='utf-8')
