Python: How to extract time date specific information from text/nltk_contrib timex.py bug

Question

I am new to python. I am looking for ways to extract/tag the date & time specific information from text eg
1.I will meet you tomorrow
2. I had sent it two weeks back 3. Waiting for you last half an hour

I had found timex from nltk_contrib, however found couple of problems with it https://code.google.com/p/nltk/source/browse/trunk/nltk_contrib/nltk_contrib/timex.py

b. Not sure of the Date data type passed to ground(tagged_text, base_date)

c. It deals only with date ie granularity at day level. Cant find expression like next one hour etc.

Thank you for your help

Answer 1

b) The data type that you need to pass to ground(tagged_text, base_date) is an instance of the datetime.date class which you'd initialize using something like:

from datetime import date
base_date = date.today()
