可定制的情境感知计算框架原型

摘要

分析现存情境感知框架的特点与不足,提出一种面向不同应用领域的可定制的情境感知框架原型,重点阐述原型的体系结构设计和软件运行时基于服务的软件架构.讨论情境感知过程中4个关键问题,包括情境感知系统的可定制化问题、情境规则的迭代与演化、情境感知的交互机制以及情境模式.最后,以该原型为基础,通过在医疗导诊场景下实现情境感知应用验证其实现领域定制的可行性.%This paper analyzes the characteristic and shortage of existing context-aware frameworks, and proposes a distinct domains oriented customizable context-aware framework prototype. The design principles of framework prototype as well as service o-riented runtime mechanism are emphasized. Then four critical issues are discussed, including framework customization, evolutionary context rules, interaction mechanism and context-usage patterns. Finally, with the basis of this framework prototype, the feasibility of distinct domains oriented is proved through the specific applications which are under healthcare service scenarios.
