Abstract: A virtual assistant system for information retrieval and management and service request processing includes a user interaction device (UID), a server computer, a system computer, and a human-controlled call center. The UID permits the user to provide voice or written instructions to the system computer via the server computer. The system computer runs artificial intelligence (AI) routines to process or preprocess commands provided into the UID by the user. When possible, the AI routines complete the requested service. Where the AI routines alone are insufficient, a human-controlled call center corrects and completes the service requests. Skilled human labor, then, is only relied upon when needed by the system. A great range of service requests can be made including, e.g.
