  1. 不是的,实体有自己的类别,默认一个实体的所有mention都是这个类别。区别:比如mention type对应“时间”,而role type是“冻结开始时间”
  2. 没看懂

1 我用一个英文数据集里面 最后把这些mention的类型打印出来看都是一样的 只有 0 1
但是原始的类型肯定不是这样
2. 举个例子:文本里面 标记的entity 一共 10个 但是事件却只有其中5个 ,或者更直接点事件里面一个都没用到
这样训练应该是可以的 但是从感觉上来说 这个多余的实体是否有必须要加入 模型里面

  1. 根据您的描述,应该是数据集处理的时候有些问题。因为是您自己的数据集,所以没办法定位到具体的问题;
  2. 都行,实验结果证明加上之后可以提升NER部分的P值。

我看有些数据里面有othertype 这个是不是就是我说的多余实体是吧 ~~~

是的,但不是“多余实体”的全部。可以对数据集做个简单分析,就可以看出哪些是“多余实体”了。
