航天产品研制中面临知识资源分散、结构化程度不高、体系化程度不够等诸多问题,需要对知识资源进行结构化处理,形成规范的知识模型,以实现后续的知识识别、解析、挖掘等。知识模型的构建与所属领域紧密相关,本文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,以文档类知识、软件类知识、图纸类知识为典型类别,基于本体思想,分析知识模型构建流程,并提出构建实例,为产品研发中知识体系的构建提供支撑。

In the aerospace product research procession, there are many problems to be faced, including knowledge resources scatter, insufficient structuring, lack of systematism etc. Thus the knowledge resource need to be structured to form knowledge model, for the sake of further knowledge discover, analysis and mining. Knowledge model is closely related to the area knowledge belongs. This paper considers the factors including knowledge classification, knowledge elements extraction, elements relation analysis, proposes principal and method of knowledge model construction, taking documental knowledge, software knowledge, and technical drawing knowledge for typical class, describes the construction process as well as detailed instance based on ontology, which can support the formation of whole knowledge system for aerospace product research.
