Language Understanding Service (LUIS)

The video tutorial covers the basics of language understanding, focusing on extracting meaning, intention, and action from text inputs. It explains key concepts like utterance, entities, and intent. The tutorial guides viewers through creating a language understanding service, building a home automation app, and training and testing the model. It also demonstrates how to publish the model and use it with both text and voice inputs. The session concludes with a review of key concepts and practice questions.
