摘　　要：为了提高刻面分类检索软构件的查准率,结合领域本体,提出了支持自然语言检索的软构件检索过程模型。该模型抽象了领域知识,形成领域本体库,用于匹配用户检索使用的自然语言,提供领域内一致认可的检索术语。该术语然后与软构件描述库中的软构件描述术语进行匹配,进而从软构件库中检索软构件。软构件描述库采用了刻面分类方法。ATS软构件检索实验结果表明,较之于传统的刻面分类方法,该检索策略既提高了检索精度,又增强了检索的灵活性。To enhance the precision of component retrieval based on facet classification, a software component retrieval process model was presented with domain ontology to support natural language retrieval. An ontology repository abstracted from domain knowledge was used to match what users input in natural language and outputs coherent retrieval terms in the domain. These terms were then used to match what component described in the component description repository with facet classification. Related software components were retrieved from the component repository. The resuits of experiments in the ATS field show that the new retrieval method can enhance the retrieval precision compared with the traditional facet classification, and that it is flexible enough because of the use of natural retrieval language.
