摘要
从基于语义的信息共享思路出发,设计了一种基于本体的面向特定领域软件需求共享系统,系统分为5层:源文档层、索引本体层、检索层、管理层、表示层.系统基于本体对需求进行语义检索,定义了需求本体系统及描述方法,本体的实例影射到按项目编目存储的需求文档.
From the view of semantic information sharing,a domain-specific requirements sharing system is designed,which is based on ontology.The system has five layers：the document resource layer,ontology index layer,search layer,management layer and interface layer.Requirement ontology system and its expression method based on NKI are defined.Instances of ontology are mapped to requirement documents,which are stored according to projects.Semantic search based on the ontology is supported.
