The Natural Language Classifier service uses advanced natural language processing and machine learning techniques to assign custom categories to inputted text. For example, you submit a question and the service returns keys to the best matching answers or next actions for your application. You create a classifier instance by providing a set of representative strings and a set of one or more correct classes for each training. After training, the new classifier can accept new questions or phrases and return the top matches with a probability value for each match.
