Looping Experta for use with a chatbot

[jnrusson1]

Hi I have a question relating to looping Experta infinitely. I am currently creating a rule based retrieval chat bot and I would like to use Experta as my Knowledge engine.

To give a quick background I need to get train ticket information from the user and use this to scrape a website. I need to assign facts based on a user input i.e assign destination, current location, date etc.

As it is a chatbot I need experta to run infinitely until it is given an instruction to break or it completes it's task. For example if the chatbot asks, "what station are you at? " and the response is not a station, then it should repeat the question.

At the moment my rules will fire once and then the process will exit. How can i implement this looping system?
