Creating a Chatbot with RiveScript in Java

Motivation "Artificial Intelligence (AI) is considered a major innovation that could disrupt many things. Some people even compare it to the Internet. A large investor firm predicted that some AI startups could become the next Apple, Google or Amazon within five years"   - Prof. John Vu, Carnegie Mellon University.

There are some existing approaches for chatbots including pattern matching, algorithms, and neutral networks.
