@blatyo Yes I’m using state machines to build the conversation (not to be confused with behaviour trees which was also talked about in the conference). More specifically, my approach is what I’ve explained briefly when I talked about BotKit. The code for BotKit, which is a WIP library that enables you to build chatbots using the state machine approach is available here.

Unfortunately the NLU training/inference was not done in Elixir. I’ve used two NLP/NLU backends to train the models required for the chatbot. Namely Wit.AI and Stanford CoreNLP. I used Wit.AI through their http api and CoreNLP using Erlang’s JInterface on a dedicated Erlang node.

I’m planning on open sourcing the chatbot code once I’m done with the project.

Speaker here. The title of talk is not the best representative of its content. It is more about helping smokers quit using chatbots and elixir. Anyway, I’m happy to discuss it here if anyone has questions.

I’d love to see more code for this. Especially the stuff used for NLP and training.
