NLP based question answering system

I was wondering as elasticsearch is very good at natural language processing, Is there any way to use it for question answering system?

Suppose I have a story following:

My name is Shahriar and I have a cat. Its name is Tom.

And so many description and detail in this story.

Question can be like:

  1. Does Shahriar have a cat?
  2. What is the name of Shahriar's cat?

Can I build something using elasticsearch to answer this question?

Can you have any suggestions for me how can I start? How to approach and what are the steps?

It's not natively, but check out https://github.com/spinscale/elasticsearch-ingest-opennlp for functionality that can be integrated.
