摘　　要：针对刻面描述的检索方法的不足,引入领域本体,提出领域本体和刻面描述相结合的构件检索模型,并对所提出的构件检索模型中的构件检索过程进行研究。分析语义推理过程,提出基于本体和刻面描述相结合的检索算法。最后,构建一个第三方物流信息化构件检索的系统对所提出的构件检索机制的检索效率进行验证分析。验证结果表明,领域本体与刻面描述相结合可以提高构件检索的查全率和查准率。Aiming at the shortages of retrieval method for facets description, we introduce the domain ontology and present a component retrieval model in which the domain ontology is combined with facets description. We also study the procedure of component retrieval in the proposed component retrieval model, analyse its semantic reasoning process, and present a retrieval algorithm which is based on the combination of ontology and facets description. In end of the article, we construct an informatisation component retrieval system for third-party logistics to have validated and analysed the component retrieval efficiency of the component retrieval mechanism proposed in the article. Validation result demonstrates that the combination of domain ontology and facets description can improve the recall and precision rates of the component retrieval.
