一种基于描述逻辑的构件检索匹配算法

Component retrieval and matching algorithm based on description logics

在基于刻面的描述方法基础上引入描述逻辑作为知识表示的形式化方法,来描述用户复用需求和构件,从而使二者能够在语义层面上进行匹配。提出了一种基于描述逻辑的构件检索匹配算法,用该算法计算出一个实数值来表示用户复用需求与某一构件的匹配度,以便帮助复用者在构件库中选择合适的构件。

Based on facet-based approach, description logics were introduced as the formal method of knowledge representation. Description logics can be used to represent users＇ reuse requirements and components, so algorithm based that they can on description match on the semantic level. A component retrieval and matching logics was proposed. The the matching degree of reuse requirement and any compo algorithm calculates a real number to denote nent. Thus the matching degree can help the user to find an appropriate component from the component library.
