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
