SYSTEM AND METHOD FOR IDENTIFYING AND ESTABLISHING PREFERRED MODALITY OR CHANNEL FOR COMMUNICATION BASED ON PARTICIPANT'S PREFERENCE AND CONTEXT

摘要

PROBLEM TO BE SOLVED: To identify and establish preferred modalities or channels for communications based on participant's preferences and capabilities. SOLUTION: In a certain approach, when accessed or inferred preference, ability and a target on the side of a contactor 120 are given, the system tries to optimize the preferences accessed the inferred or directly on the side of the contactor 120 and keeps the rationality and context of privacy, on the side of a contactee. Such optimization can be achieved using preferences and policies concerning the preference and tried contact by inferring the context, contents and a task under uncertainty, based on deterministic specification or by using deterministic specification, to maximize the expectation utility of communication to the side of the contactee 130.
