上下文感知是当今面向服务的Web环境中一个无所不在的主题，但仍在进行深入研究，以实现非形式和普遍的适用性。许多方法仍然依赖于应用程序，或者需要用户定义复杂的配置文件、语义服务描述或规则。在本文中，我们将介绍一种方法，应简化上下文感知服务的原型，并允许快速适应新的应用领域。为此，我们定义了上下文函数的概念，并描述了一个适当的框架和语义数据模型。我们的尽力而为的方法考虑不完整的上下文信息，可以灵活地联合收割机不同类型的上下文数据，并允许纳入机会建模动态服务行为。语义Web技术被用来轻松地定义和解耦上下文感知的描述从实际的服务逻辑。
Context-awareness is an omnipresent topic in today's service-oriented Web environment, but is still highly researched to enable a un form and pervasive applicability. Many approaches are still application dependent or require the user to define complex profiles, semantic service descriptions, or rules. In this paper, we introduce an approach that should ease the prototyping of context-aware services and allow for a fast adaptation to new application areas. For this purpose, we define the notion of context functions and describe a proper framework and semantic data model. Our best-effort approach considers incomplete context information, may flexibly combine different types of context data, and allows for the incorporation of chance to model dynamic service behavior. Semantic Web technology is utilized to easily define and decouple context-aware descriptions from the actual service logic.
