Chatbot framework with intent extraction from data

Hey! I am quite experienced with ML but I am making first steps with chatbots. I am trying to create simple chatbot around some topic. I have quite large database of sample conversations. Coming from ML background I suspected there would be some chatbot framework that supports most common intent extraction from provided dataset. That’s not the case, at least in Dialogflow. That really surprised me, I imagined that it’s pretty basic functionality for a chatbot – to extract intents from thousands of messages.

That’s why I came here, maybe I understood something wrong about DF or there are no such solutions. Can you tell me if there are existing frameworks which do intent extraction from dataset?
