python - 使用文本特征提取创建数据集

Question

我正在尝试从恐怖事件的文本数据中提取一些特征来创建数据集。使用名称实体识别，我已经成功提取了名称、地点、组织等特征，现在我想提取参与事件的成员数量。

The 2008 Mumbai attacks (also referred to as 26/11) were a series of terrorist attacks that took place in
November 2008, when 10 members of Lashkar-e-Taiba, a terrorist organization based in Pakistan,
carried out 12 coordinated shooting and bombing attacks lasting four days across Mumbai.

如何从上面的文本中提取10名虔诚军成员并将10放入攻击者数量栏中。使用 nlp 技术是否可以实现这一点？

Answer 1

对您的情况有用的两种技术是 - 依赖项解析和语义角色标记。您可能还想查找基于方面的情感分析。所有这三个都可以帮助识别句子中单词之间的关系。
