Semantics: Teleaction Objects

Teleaction Objects (TAOs) possess private knowledge specific to the object instances. The user can create and modify the private knowledge of a Teleaction Object, so that the Teleaction Object will automatically react to certain events to pre-perform operations for generating timely response, improving operational efficiency and maintaining consistency. Moreover, Teleaction Objects also possess a hypergraph structure leading to the effective presentation and efficient communication of multimedia information. The Active Multimedia System (AMS) is designed to manage the Teleaction Objects. In the AMS, the private knowledge of each Teleaction Object is realized by the index cells of Active Index. The applications to smart multimedia mail and multimedia information retrieval are described to illustrate the usefulness of Teleaction Objects.
