How to implement a java chatbot using Rapidminer?

Hi!  I would like to write a Java program (a chatbot) with machine learning\IA features (like TextMining)  using RapidMiner API for Java: this chatbot would implement an interactive  service desk  for users that need computer support.  So you could make a request computer support to the chatbot and he would reply  with a possible solution checking also all the solutions already implemented for similar problem checking all the possibile channels of support (like FAQ, web service desk platform like Footprint, etc) .  In this way I will not implement the machine/learning IA features chatbot  by scratch. Can someone tell me some details of which steps to follow to implement this? Thanks. Luca
