摘要

普及应用程序希望以简单的方式描述它们需要关于用户的上下文信息，并在低层上下文匹配由语义表达式定义的指定约束时得到通知。在本文中，我们报告了在两个欧洲资助的项目中实现上下文查询语言并在实际上下文框架中使用它来支持移动上下文感知应用程序的经验。我们的经验表明，语言设计及其实现都适合于支持应用程序的复杂异步高级上下文通知需求。

High level context query processing: An experience report

Pervasive applications want to describe in simple ways which context information they need about users, and be notified when low level context matches specified constraints defined by semantic expressions. In this paper we report our experience while implementing our Context Query Language and using it in a real context framework to support mobile context-aware applications in two European-funded projects. Our experience has shown that both the language design and its implementation are suitable to support complex asynchronous high-level context notification requirements from applications.
