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
