Abstract: A system for performing instructions determined by received media-based messages, the system including an interface for receiving a media-based message from a system user; a database associating a plurality of specifications of media-based messages with respective stored instructions; a recognition engine for identifying a correspondence between a received media-based message and a stored specification of a media-based message. The system may include an instruction engine for performing an instruction associated with a stored specification of an media-based message for which a correspondence has been identified; an interface for receiving an activation request; and a database manager configured to process the activation request to generate publication data for creating a publication that may be recorded by a user to define a new media-based message and configured to adapt the database to include a specification of the new media-based message.
