Reference documentation and code samples for the Google Cloud Dialogflow V2 Client class KnowledgeBase.
A knowledge base represents a collection of knowledge documents that you
provide to Dialogflow. Your knowledge documents contain information that may
be useful during conversations with end-users. Some Dialogflow features use
knowledge bases when looking for a response to an end-user input.
For more information, see the knowledge base
guide.
Note: The projects.agent.knowledgeBases resource is deprecated;
only use projects.knowledgeBases.
