Development and creative thinking of dynamic semantics 动态语义学的发展和创新思维
A clearly defined dynamic semantic framework 一种清晰定义的动态语义框架
From drt to sdrt-new development of the theory of dynamic semantics 动态语义理论的新发展
In the uml specification, the editors describe the static semantics in formal language ocl ( object constraint language ) and natural language, while the dynamic semantics is almost described in natural language . uml lacks in a strict definition of dynamic semantics 在uml规范中,编制者是用较为形式化的语言ocl(objectconstraintlanguage)和自然语言两种手段描述静态语义,而动态语义却基本上完全是用自然语言来描述的,uml缺乏一个严格的动态语义定义。

We use temporal logic language xyz / e as our component description language for components may have different abstract hierarchy and different granularity . xyz / e is able to describe the dynamic semantics and static operations of component, and to formally describe system in different hierarchy 由于构件可能具有不同的抽象层次和粒度,我们采用了时序逻辑语言xyze作为构件描述语言,这种语言能够描述构件的静态语义和动态执行,并且能在不同抽象层次上对系统进行形式化描述。
According to the characteristics of workflow process execution, a kind of reactive activity-centered process meta-model is defined and a kind of graphical notation is provided for it, at the same time, for this meta-model, a kind of dynamic semantics is specified, which represents the runtime behavior of the process and can be expressed as a finite state automata . finally, an example is given to illustrate how to apply it to analyze the semantic correctness of process models 根据过程执行的特点,定义了一种以活动为中心的反应式过程元模型,并为其提供了一种图形表示,同时为此元模型指定了一种体现过程运行时行为的动态语义,该语义可表示为一个有限状态自动机.最后举例说明了如何应用它分析过程模型的语义正确性
