摘要
近年来,本体已成为需求工程中重要的研究方向。关于本体的研究包含两个重要课题:本体描述语言和本体构造工具。目前本体描述语言和构造工具在设计和使用上存在两方面不足:一是本体描述语言多基于复杂的语法和逻辑,最终用户直接使用较困难;二是多数本体描述语言和构造工具,只提供本体的表示和浏览,不能较好支持本体的重用的可编程操作。针对以上问题设计了一种类自然语言的本体描述语言PNL-ODL(PseudoNaturalLanguageOntologyDe-scriptionLanguage),设计并实现了基于PNL-ODL的本体构建工具。文章详细介绍了PNL-ODL的设计思路和构建工具的开发思路,通过构建组织本体,说明PNL-ODL和配套工具的使用方法。利用PNL-ODL和本体构建工具,领域专家可以用类自然语言的方式方便地书写领域本体文档;并借助本体构建工具将领域本体的文档转化为可供检索和重用的结构化本体库。
In recently years,ontology has become one of the most important disciplines in the fields of Requirement Engineering.Many experts focus their mind on the subjects of ontology language and ontology building.However,now, there are two problems in this field,First of all,it is difficult for common users to use the ontology languages,most of which are based on complex syntax and logic.The second,usually,the ontology building tools,which lack of function to support reuse and program on the ontology base,can only support ontology representation and terms browsing.This paper reports on a new ontology language,named PNL-ODL（Pseudo Natural Language Ontology Description Language） and an ontology building tools based on PNL-ODL,designed and developed in our lab.PNL-ODL can easily be used by people lack of knowledge on computer science and on support of the ontology building tools user can build the ontology base conveniently.Furthermore,we also introduce the organization ontology,which is represented in PNL-ODL,to discuss the reusable ability of ontology.
