Adding NLP classifiers (modules as labels)

[waelbenamara]

Feature description:

Adding an NLP unit that classifies user‘s request to one of the modules.
Suggesting this feature is due to the fact that when a user sends a greeting (for example) but in different forms other than mentioned in the modules, it fails to return the accurate response.

How to implement it ?

Make a NLP classifier that classifies the request to one of the corresponding module.
We may use nltk or similar libraries.
