- * Service Description: Agents are best described as Natural Language Understanding (NLU) modules
- * that transform user requests into actionable data. You can include agents in your app, product,
- * or service to determine user intent and respond to the user in a natural way.
- *
- * <p>After you create an agent, you can add [Intents][google.cloud.dialogflow.v2beta1.Intents],
- * [Contexts][google.cloud.dialogflow.v2beta1.Contexts], [Entity
- * Types][google.cloud.dialogflow.v2beta1.EntityTypes],
- * [Webhooks][google.cloud.dialogflow.v2beta1.WebhookRequest], and so on to manage the flow of a
- * conversation and match user input to predefined intents and actions.
- *
- * <p>You can create an agent using both Dialogflow Standard Edition and Dialogflow Enterprise
- * Edition. For details, see [Dialogflow
- * Editions](https://cloud.google.com/dialogflow/docs/editions).
- *
- * <p>You can save your agent for backup or versioning by exporting the agent by using the
- * [ExportAgent][google.cloud.dialogflow.v2beta1.Agents.ExportAgent] method. You can import a saved
- * agent by using the [ImportAgent][google.cloud.dialogflow.v2beta1.Agents.ImportAgent] method.

- * <p>Dialogflow provides several [prebuilt
- * agents](https://cloud.google.com/dialogflow/docs/agents-prebuilt) for common conversation

- * Service Description: 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.v2beta1.Sessions.DetectIntent] (or
- * [StreamingDetectIntent][google.cloud.dialogflow.v2beta1.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).
- *
- * <p>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.
- *
- * <p>&#42; &#42;&#42;Contexts&#42;&#42; - 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".
- *
- * <p>&#42; &#42;&#42;Events&#42;&#42; - 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.
- *
- * <p>&#42; &#42;&#42;Training phrases&#42;&#42; - provide examples of user input to train the
- * Dialogflow API agent to better match intents.
