Is it possible to make the text summarization Abstraction Based?

[JafferWilson]

I was going through the summarizer that you included in your repository. It works fine as based on Extraction methodology.
I have a question. Whether you can make it abstraction based so that it will look more novel and will generate sentences or twist sentences that will make it look new in the summary?
Can you tell me if you can make it possible. It will be helpful.
