Power Virtual Agents #9: Entities for Conversation in chatbot

Introduction

Natural language understanding is the ability for Power Virtual Agents to understand what the user is telling it. The bot is able to route the user to the topic related to, even if that exact phrase isn’t listed as a trigger phrase.

An entity represents a real-world subject, such as a phone number, zip code, city, or even a person’s name. Your bot can smartly recognize the relevant information from user input and save it for later use

There are two types of entities:
• Pre-built entities represent the most commonly used information, such as age, colors, numbers, and names. Power Virtual Agents bots recognize these automatically.
• Custom entities are entities you make. While the pre-built entities cover commonly used information types, sometimes you’ll need to teach the bot’s language understanding model some domain-specific knowledge. For instance, you may need to create a custom entity for your product types
