Empathic Chatbots -- NLML

In NLP we use sentiment to refer to the positive or negative emotions a person expresses in their language. It may be measured categorically (negative) or numerically (-1.2). It may be measured at the utterance level or as applied to a particular entity or topic. It may be calculated via any number of algorithms, but from the standpoint of a user of text analytics software, you provide text to a program and get back information about the sentiment. When you design the conversational paths of your chatbot you are concerned primarily with the topics of conversation.
