Question

The customer service of your company spends a lot of time answering the same questions. They asked you to help them to automate this process. They provided you a Microsoft Excel (*.xlsx) document with frequently asked questions and typical answers. What service will you use to create a knowledge base from this document?

Options

  • AAzure Bot Service
  • BCustom vision
  • CText Analytics
  • DQnA Maker
  • ELUIS

Explanation

To automate answering frequently asked questions from an Excel document, Azure AI QnA Maker is the appropriate service for creating a knowledge base.

Common mistakes.

  • A. Azure Bot Service is a platform for building, connecting, and managing bots, but it relies on services like QnA Maker to provide the knowledge base content.
  • B. Custom Vision is an AI service for image recognition and object detection, which is unrelated to creating a text-based knowledge base from an FAQ document.
  • C. Text Analytics (now Azure AI Language service) provides capabilities like sentiment analysis or key phrase extraction, but not the direct creation of a knowledge base for question-answering from an FAQ document.
  • E. LUIS (Language Understanding Intelligent Service) is used for understanding user intent and entities in natural language, not for building a knowledge base from a document of predefined questions and answers.

Concept tested. QnA Maker for knowledge base creation
