For those of you who are interested in chatbots and Ruby, we open sourced Clarke, the framework we are using at Applidium to architecture them: https://github.com/applidium/clarke

And if you're more interested in the thought process behind, we did a presentation of what led us to this architecture https://docs.google.com/presentation/d/1kGiHfMMjf-OL7ZUODttu...

If you have any question or feedback they're very welcome :-)
