Abstract: In one embodiment, a method includes receiving a user input by a user from a client system associated with the user at a current time, parsing the user input to identify intents and slots associated with the user input, determining that one or more of the identified intents or slots are volatile based on whether the respective intent or slot resolves to information that is subject to change within a threshold timeframe of the current time, requesting information from an agent to resolve the user input, the information including (1) current information that resolves the intents and slots associated with the user input and (2) volatility information associated with the intents or slots determined to be volatile, generating a response to the user input including the requested information from the agent, and sending, to the client system, instructions for presenting the response to the user.

Abstract: In one embodiment, a method includes receiving a user query inputted on a head-mounted device from the head-mounted device, wherein the user query corresponds to multiple dialog-intents, executing multiple tasks corresponding to the multiple dialog-intents, generating a multi-perspective response by a stitching model based on two or more of execution results of the multiple tasks, wherein the stitching model combines the two or more of the execution results based on natural language processing, and wherein the multi-perspective response comprises a natural-language response combining the two or more execution results, and sending instructions to the head-mounted device for presenting the multi-perspective response on the head-mounted device.
