serverless-simple-nlp-demo

This is a project intended to demostrate that Natural Language Parsing is not an impossible task to be left only to Google, Facebook, Amazon and the link. Given a small enough subject area/domain, it is possible to achieve decent parse results.

This demo uses the context of house hunting as an example for some simple Natural Language Processing, running on Amazon's Lambda service.

Accompanying series of blog posts for this code can be found at link coming soon!
