Benefits

Add natural language understanding to your apps

Designed to identify valuable information in conversations, Language Understanding interprets user goals (intents) and distills valuable information from sentences (entities), for a high quality, nuanced language model. Language Understanding integrates seamlessly with the Speech service for instant Speech to Intent processing, and with the Azure Bot Service, making it easy to create a sophisticated bot.

Quickly build a custom language solution

Powerful developer tools are combined with customizable pre-built apps and entity dictionaries, such as Calendar, Music, and Devices, so you can build and deploy a solution more quickly. Dictionaries are mined from the collective knowledge of the web and supply billions of entries, helping your model to correctly identify valuable information from user conversations.

Always learning and improving

Reinforcement learning is used to continuously improve the quality of the natural language processing models. Once the model starts processing input, Language Understanding begins active learning, allowing you to constantly update and improve the model.

Enterprise-ready, available worldwide

The service is ready to be deployed in commercial applications and can scale with enterprise quality and performance. The service meets international compliance standards and supports 12 languages—making it highly accessible.

  2. 2 Azure Active Directory validates the employee’s identity
  3. 3 The employee can ask the bot what type of queries are supported
  4. 4 Cognitive Services returns a FAQ built with the QnA Maker
  5. 5 The employee defines a valid query
  6. 6 The Bot submits the query to Azure Search which returns information about the application data

Chatbot de comércioJuntos, o Serviço de Bot do Azure e o serviço de Reconhecimento Vocal permitem que os desenvolvedores criem interfaces de conversação para vários cenários, como bancos, viagens e entretenimento. Por exemplo, o concierge de um hotel pode usar um bot para aprimorar as interações tradicionais de email e chamada telefônica ao validar um cliente por meio do Azure Active Directory e usar os Serviços Cognitivos para melhor processar as solicitações dos clientes de forma contextual usando texto e voz. O serviço de reconhecimento de fala pode ser adicionado para dar suporte a comandos de voz.1234567

Commerce chatbot

Overview

Together, the Azure Bot Service and Language Understanding service enable developers to create conversational interfaces for various scenarios like banking, travel, and entertainment. For example, a hotel’s concierge can use a bot to enhance traditional e-mail and phone call interactions by validating a customer via Azure Active Directory and using Cognitive Services to better contextually process customer requests using text and voice. The Speech recognition service can be added to support voice commands.

Flow

  1. 1 Customer uses your mobile app
  2. 2 Using Azure AD B2C, the user authenticates
  3. 3 Using the custom Application Bot, user requests information
  4. 4 Cognitive Services helps process the natural language request
  5. 5 Response is reviewed by customer who can refine the question using natural conversation
  6. 6 Once the user is happy with the results, the Application Bot updates the customer’s reservation
  7. 7 Application insights gathers runtime telemetry to help development with Bot performance and usage

"It's amazing, once development started, how quickly the whole thing came together… We didn't need to build any special functionality to connect the bot to our product catalog and stock data—we just used existing feeds."
