上下文的概念以各种形式出现在包括计算机科学在内的几个学科中。在本文中，我们关注的概念建模领域的上下文的概念。首先，我们提出了一个简单的定义，上下文被看作是一组对象，其中每个对象都有一组名称和可能的引用：对象的引用是另一个上下文，它“隐藏”有关对象的详细信息。然后，我们通过传统的抽象机制（即分类、概括和属性）来构建其内容，从而增强了我们简单的上下文概念。我们表明，根据应用程序的不同，我们的上下文概念可以用作建模的替代方式，也可以用作传统抽象机制的补充。最后，我们研究了语境化和传统的抽象机制之间的相互作用，以及制约这种相互作用。
The notion of context appears in several disciplines, including computer science, under various forms. In this paper, we are concerned with a notion of context in the area of conceptual modeling. First, we present a simple definition whereby a context is seen as a set of objects, within which each object has a set of names and possibly a reference: the reference of the object is another context which “hides” detailed information about the object. Then, we enhance our simple notion of context by structuring its contents through the traditional abstraction mechanisms, i.e. classification, generalization, and attribution.We show that, depending on the application, our notion of context can be used either as an alternative way of modeling or as a complement of the traditional abstraction mechanisms. Finally, we study the interactions between contextualization and the traditional abstraction mechanisms as well as the constraints that govern such interactions.
