如何使用 NLP 和深度学习技术从原始非结构化文本创建域规则？例如，对于下面关于登革热症状的文本，所有三个看起来都非常相似，但是如果您想确定一个人是否患有登革热，您需要从这些原始文本中确定明确的共同最低限度规则，以确认一个人是否患有登革热登革热。有人可以参考一些解决了类似问题的研究或博客吗？

1) Symptoms of dengue fever include severe joint and muscle pain, swollen lymph nodes, headache, fever, exhaustion, and rash. 

2) High fever and at least two of the following:
Severe headache
Severe eye pain (behind eyes)
Joint pain
Muscle and/or bone pain
Rash
Mild bleeding manifestation (e.g., nose or gum bleed, petechiae, or easy bruising)
Low white cell count

3) Aching muscles and joints
Body rash that can disappear and then reappear
high fever
intense headache
pain behind the eyes
vomiting and feeling nauseous

对于上述三个提取公共规则看起来像

1) Fever
2) Joint and muscle pain
3) Headache
