METHOD FOR RULE-BASED CONTEXT ACQUISITION

摘要

Disclosed herein are methods and systems for rule-based context acquisition. The method includes accepting a request for a target context from an application in a context acquisition system and identifying a context rule associated with the target context using a rule-based inference cache. The method also includes determining an inferred value of the target context based on the previously obtained context and context rules. If the inferred value of the target context cannot be determined, the method executes the first step of the sensing plan to obtain the inferred value of the target context using the rule-based acquisition planner and the inferred value of the target context. And executing any of a plurality of subsequent steps of the sensing plan until this is obtained.
