Abstract: The present disclosure is directed to an on-demand intelligent assistant that obtains physical identifiers of a target individual using information received from sensors. The assistant determines an identity of the target individual using the physical identifiers. The assistant also caches the physical identifiers and the identity as baseline information of the target individual. The assistant further detects keywords used in communications of a user with the target individual. Moreover, the assistant determines that the user desires additional information of the target individual based on the keywords. Additionally, the assistant determines a query for the additional information using the baseline information and the keywords. Further, the assistant retrieves the additional information from a remote database using the query and provides the additional information to the user.
