Python-HeidelTime

This is a python wrapper for the multilingual temporal tagger HeidelTime.

For more information about this temporal tagger, please visit : https://github.com/HeidelTime/heideltime

Heideltime needs a Part Of Speech Tagger, by default it uses TreeTagger : http://www.cis.uni-muenchen.de/~schmid/tools/TreeTagger/. This repo includes TreeTagger scripts for Mac and Linux. Windows users will have to download the appropriate scripts from the TreeTagger home page.

❗ Disclaimer: this repository is not maintained, you are free to use it and adapt it to your needs but you may not get support if needed.

Demo

Clone the current github repo: git clone https://github.com/amineabdaoui/python-heideltime
Install its requirements: pip install -r requirements.txt
Create a python file in the same directory with the following code:

import HeidelTime
hw = HeidelTime.HeidelTimeWrapper('english')
hw.parse('Neil Armstrong was born in 1930')

Future Work

Encapsulate the returned tagged string in a python object
Find a way to install the appropriate POS tagger files according to the user OS.
Package all the necessary parts in the same python package and release it on PyPi.

Pull requests are welcome to improve this wrapper (which is in an early stage).
