Machine Comprehension on Chatbots08 Jul 2017
One of the most demanded feature in chatbots is the ability to automatically provide helpful informations. Users might ask about how to pay the purchases online, how to return an defected item, when the purchase could be delivered or just about the opening hours of a shop.
One way to implement this feature is to train a sentence classifier for a determined set of questions the merchant is willing to answer. The system should be instructed on some examples such as: “which credit card do you accept?”, “How do I pay?”, “which payment do you support?” and so on. This simple technique requires a sequence of manual tasks for every conversational agent, such as set up the training and inference pipeline for questions/answers, or reuse the Natural Language Understanding (NLU) system already adopted by the chatbot, if present.
