Build a Food-Searching Chatbot in Hours

Chatbots are conversational user interfaces increasingly popular in many applications such as IT service desk, customer service, sales support, commerce, advisory services, etc. There are two types of chatbots, i.e., generalist and task-oriented bots. Generalist chatbots are all-purpose and complex, e.g. Siri, which requires knowledge in many domains. Task-specific bots are much simpler but work efficiently within certain areas such as FAQ.
