        # An intent represents a mapping between input from a user and an action to
        # be taken by your application. When you pass user input to the
        # {Google::Cloud::Dialogflow::V2::Sessions::DetectIntent DetectIntent} (or
        # {Google::Cloud::Dialogflow::V2::Sessions::StreamingDetectIntent StreamingDetectIntent}) method, the
        # Dialogflow API analyzes the input and searches
        # for a matching intent. If no match is found, the Dialogflow API returns a
        # fallback intent (`is_fallback` = true).
        #
        # You can provide additional information for the Dialogflow API to use to
        # match user input to an intent by adding the following to your intent.
        #
        # * **Contexts** - provide additional context for intent analysis. For
        #   example, if an intent is related to an object in your application that
        #   plays music, you can provide a context to determine when to match the
        #   intent if the user input is "turn it off". You can include a context
        #   that matches the intent when there is previous user input of
        #   "play music", and not when there is previous user input of
        #   "turn on the light".
        #
        # * **Events** - allow for matching an intent by using an event name
        #   instead of user input. Your application can provide an event name and
        #   related parameters to the Dialogflow API to match an intent. For
        #   example, when your application starts, you can send a welcome event
        #   with a user name parameter to the Dialogflow API to match an intent with
        #   a personalized welcome message for the user.
        #
        # * **Training phrases** - provide examples of user input to train the
        #   Dialogflow API agent to better match intents.
        #
        # For more information about intents, see the
        # [Dialogflow
        # documentation](https://cloud.google.com/dialogflow/docs/intents-overview).
