上下文不一致性检测及消除的研究

Research on Context Inconsistency Detection and Resolution

在普适计算环境下,由于获得的上下文信息存在不一致性,使得上下文感知应用无法正常进行响应。研究了普适计算环境下的上下文不一致性的检测及消除,针对其提出了基于置信度数据库的反馈机制,并且丰富和扩展了上下文不一致性的消除算法。实现了相关算法,并通过实验给出了各个算法的效率和正确性的比较。

The context-aware system requires detection and resolution of context inconsistency,which exists in pervasive computing.Detection and resolution of context inconsistency was studied,a feed-back mechanism based on confidence measure database was presented,and the elimination resolution was enriched and extended in these ways.Also,we accomplished these resolutions,and their performances were evaluated through a series of experiments.
