Dialogflow Building Block, 1
Intent
Intents are the goals of the user that are expressed to the agent. In the previous examples, despite their different framing, the user was expressing a desire to know what the weather will be. That is their intent
Entities
Sometimes, users' intents are more specific, and have an intent based around a certain item or entity.
Entities allow for more specificity of requests, without exploding the intent space
What is the weather like today in Seattle?
The intent: weather inquiry; entity: Seattle
