# How to extract specific information from raw , unstructured text using NLP and Deep Learning?

I have data coming from different sources having similar information like the below example where different sources want to specify the age criteria. Is there a NLP or Deep learning based approach which I can use to extract the age rule as shown below from raw unstructured text.

A Criteria
Applicants should be above 21 years of age and up to 65 years or less at the time of maturity.

B Criteria
You are between 25-58 years of age.

C Criteria
Age of the all applicants should be between 21 and 65 .

A Rule
age >=21 AND age <= 65

B Rule
age >=25 AND age <= 58

C Rule
age >=21 AND age <= 65


 above 21 years
