基于本体的军事装备知识建模及分析

针对本体建模过程中不同受众具有不同应用需求的问题，结合本体建模七步法和软件开发螺旋模型提出基于需求的螺旋反馈法。首先，明确领域知识范畴和用户需求，进行本体总体设计；其次，领域专家依据本体构建原则评估知识体系；再次，组装知识体系模型，定义本体属性，创建实例，完成本体详细设计；最后，用户评估反馈，进行新一轮的增量迭代，直至形成正确可用的知识体系。与七步法相比，所提方法强调本体测试和用户需求，以小的分段来构建领域知识模型。此外，运用该方法实现的军事装备知识体系面向作战需求，为军事作战提供强有力的理论支撑。

Ontology Based Knowledge Modeling and Analysis of Military Equipment

Aiming at the problem that different audiences have different application requirements in the process of ontology modeling, a demand-based spiral feedback method is proposed by combining the seven-step method of ontology modeling with the spiral model of software development. Firstly, we clarify the domain knowledge category and user needs, and carry out the overall ontology design; secondly, the domain experts evaluate the knowledge system according to the principles of ontology construction; and then, we assemble the knowledge system model, define the ontology attributes, create examples, and complete the detailed ontology design; finally, user’s evaluation results are fed back, a new round of incremental iterations starts until a correct and usable knowledge system is formed. Compared with the seven-step method, the proposed method emphasizes ontology testing and user requirements, and constructs domain knowledge models with small segments. In addition, the military equipment knowledge system realized by this method is oriented to combat needs and provides strong theoretical support for military operations.
