LUIS (Language Understanding Intelligent Service)

LUIS (Language Understanding Intelligent Service) is a Microsoft Azure-based tool that helps developers create software capable of understanding natural language input. It enables applications to interpret what users mean when they type or speak, by analyzing phrases and extracting key information like intents (what the user wants to do) and entities (specific details). For example, in a travel booking app, LUIS can understand commands like "Book a flight to Paris next Monday" by recognizing the intent to book travel and identifying details like destination and date. It simplifies building conversational interfaces that feel natural and intuitive.
