// 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
// [DetectIntent][google.cloud.dialogflow.v2.Sessions.DetectIntent] (or
// [StreamingDetectIntent][google.cloud.dialogflow.v2.Sessions.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-enterprise/docs/intents-overview).
