I am doing some research about chatbots and more specifically Dialogflow. When I was searching for the intent classification I find out that Dialogflow is using rule-based grammar matching and ML matching. I tried to find more information about the rule-based grammar matching but I couldn't find anything... Is this the same as dependency parsing? Can someone help me with some useful sources where I can get more information about how this alogritme is working?
Thanks in advance!
