摘要
根据构件模型的研究现状,针对目前的构件描述模型缺乏语义描述的支持,在刻面分类模式的基础上,提出了基于语义扩展的构件描述模型,采用OWL本体语言对构件本体的知识框架做了描述,并将此构件模型应用于教学评估系统,构造出了基于语义的软件构件检索体系构架,实现了对领域构件进行语义查询的目的。通过实验证明,该模型提高了构件检索的查全率和查准率。
According to the current research status of component model, the present component description model is lack of semantic description. Combining the facet classification, the component description model based on semantic expansion is proposed, and the knowledge frame of the component ontology is descripted by usmg u w L ~weo umu,u^y ,,~,6^-~ r the existing TACR （teacher appraised component repository）, and the retrieving software components architecture based on semantic is proposed which gaining the purpose of retrieving the domain components by semantic. The experimental results show that the recall ratio and the accuracy ratio are improved obviously.
