My question is about chat-bots. I need an academically-oriented question answering system that works like IBM Watson.
More specifically, this QA should accept a typed-in question from a user and search the correct answer in an appropriate textbook in PDF format.
For example, the user types "What is the difference between RNA and DNA?", and the question answering system will search a textbook of molecular biology in a PDF format, construct and fetch the correct answer to the user.
