推荐答案
这种情况正是我目前在公司工作的情况.我们需要提取标题下的文本.我个人使用的是基于规则的系统，即在逐行阅读整个文档后，使用正则表达式来识别所有编号的标题.找到标题后，请输入要为其找到相应段落的标题的名称.此输入与现有的标题列表匹配，并使用通用句子编码器找到最接近的匹配项.之后，我只显示从该标题到下一个标题的所有内容.
This scenario is exactly what I am working on in my current company. We need to extract text lying under a heading. I'm personally using a rule based system i.e, using regex to identify all the numbered headings after reading the entire document line by line. Once I have the headings I enter the name of the heading for which I want to find the corresponding paragraph. This input is matched with the pre-existing list of headings and using universal sentence encoder I find the nearest match. After that I just display all the contents that is present from that heading upto the immediate next heading.
