Various categorizations of context have been proposed in the past. Dey and Abowd (1999)Towards a Better Understanding of Context and Context-Awareness distinguish between the context types location, identity, activity and time. Kaltz et al. (2005) identified the categories user&role, process&task, location, time and device to cover a broad variety of mobile and web scenarios. They emphasize yet for these classical modalities that any optimal categorization depends very much on the application domain and use case. Beyond more advanced modalities may apply when not only single entities are addressed, but also clusters of entities that work in a coherence of context, as e.g. teams at work or also single bearers with a multiplicity of appliances.

过去已经提出了各种各样的上下文分类。为了更好地理解语境和语境感知，区分语境类型、位置、身份、活动和时间。Kaltz et al.(2005)确定了用户与角色、流程与任务、位置、时间和设备的类别，以涵盖各种各样的移动和网络场景。他们还强调，对于这些经典模式，任何最佳分类都非常依赖于应用程序领域和用例。除了更先进的模式之外，如果不仅涉及单一实体，而且涉及在一致背景下开展工作的多个实体，例如:。团队在工作或也与多种器具的单身搬运人。

目前，有很多情景分类的方法。 Dey and Abowd (1999)对情景中的位置、身份、活动和时间进行了区分；Kaltz et al.(2005)将移动设备和网络场景考虑在内，确定了用户与角色、流程与任务、位置、时间和设备的分类方法。他们还强调，对于这些经典模式，任何最佳分类都非常依赖于应用程序领域和实例。除了更先进的模式之外，如果不仅涉及单一实体，而是在一致背景下开展工作的多个实体，例如:团队协作或多任务处理。
