The Natural Language Classifier service understands the intent behind text and returns a corresponding classification, complete with a confidence score. For example “What is the weather like today? or “Is it hot out?” or “Is it going to be nice today?” are all ways of asking about “temperature”. Use NLC to answer questions in a contact center, create chatbots, categorize volumes of written content and more.
