Various system embodiments of the present invention are directed to an automated concierge system through which users of the automated concierge system can request and obtain many types of information and services. Unlike traditional search engines and electronic query-processing interfaces, the automated concierge systems provide much greater flexibility with respect to means of access, including types of electronic devices and communications media that can be used to access the concierge services, greater flexibility in the timing of responses to information and service requests, more efficient information and service provision, and access to a much broader range of information sources and service providers. The automated concierge systems that represent embodiments of the present invention provide state-associated searches, in contrast to the stateless searches generally provided by search engines and many electronic query-processing interfaces, and employ a generally asynchronous message-based interface, rather than the rigid request/response interfaces provided by traditional search engines and other electronic query-processing systems.
