摘　　要：知识模型的构建与所属领域紧密相关。面对航天产品研制中存在的知识资源分散、结构化和体系化程度不够高等诸多问题,面向航天领域的知识资源,从知识分类、知识要素提取、要素间关系分析等维度提出知识模型构建原则和方法,同时按照载体形式的不同分为文档类知识、软件类知识、图纸类知识和实物类知识等知识类别,探讨不同类别知识的属性要素及其关键要素的提取;进一步基于本体思想分析知识模型构建流程,并以单类别知识模型和综合性知识模型构建作为具体实例进行分析,为支撑航天产品研发中的知识体系构建提供参考。The construction of knowledge model is closely related to the specific knowledge field.This paper is oriented towards problems such as scattered knowledge resources,low degree of structuring,and insufficient degree of systemization etc.existing in the development of space products,facing the knowledge resources in the aerospace field,proposes the principles and methods of knowledge model construction from the dimensions of knowledge classification,knowledge element extraction,and relationship analysis between elements.It classifies aerospace knowledge as document knowledge,software knowledge,technical drawing knowledge,product model knowledge etc.,towards differen categories,corresponding properties and extraction method is analyzed.Further,the knowledge model construction process is decribed based on ontology idea,then construction instances of single-catogery knowledge model and muti-catogery knowledge model are both elaborated,which can provide support reference for the construction of knowledge system in aerospace product development.
