How to compare a sentence with a paragraph and get its probability in terms of correctness? This is my first post on stackoverflow network and I am dealing with a machine learning.

Lets say I have a paragraph describing a rabbit and tortoise story. The story concludes that tortoise is a winner.

Now I want to train ML engine based on this paragraph. If I provide a statement as "Rabbit won the race", how can it show me the correctness of my statement in terms of probability of correctness?

Need help.
This is a complex problem related to Natural Language Understanding (NLU). The key part in such a system is certainly textual entailment, but it could also use techniques such as Question Answering and summarization.

I'm not aware of any direct model or tool to carry out this task exactly, so I think you will have to study the literature in these fields.
