基于领域特征空间的构件语义表示方法

Domain Feature Space Based Semantic Representation of Component

在基于构件的软件开发范型中,构件模型是构件分类、检索和适应等关键任务的理论基础,然而构件模型中的语义表示方法一直是一个难点.提出一种以语义为核心的构件模型,采用基于领域分析的特征空间语义定义方法,从领域空间、定义空间和语境空间三个方面刻画语义结构,用描述逻辑表达语义内容及实现自动推理,尤其是文中的构件语义体概念和特征空间形式化方法,为构件复用自动化和工程化提供了一种可能的解决途径.

In the paradigm of component-based software development, the component model is regarded as the foundation of almost all tasks such as classification, retrieval and adaptation. However, to date the semanticrepresentation of component is a critical problem in the model. In this paper, a semantics intensive component model is proposed. Through a semantics defining method in principle of domain analysis on the feature space, the three views of component, that is domain space, define space and context space, are suggested to describe the semantic structure, and the feature description logics is used to express the semantic content. Especially, both the concept of semantisizer and formal method of the feature space are one possible solution to component reuseautomation and engineering.
