| 摘 要： | 知识管理系统的首要问题是知识建模,知识模型直接影响着整个系统知识的获取、共享、重用和推理。文章运用领域本体思想对锻造知识进行分类、总结,提出一种基于本体元模型驱动的锻造知识管理模型,初步构建了锻造知识领域本体,采用框架概念图表示锻造知识。文章还结合锻造工艺知识,给出了本体元模型驱动和概念图框架知识表示模型在锻造知识管理中的具体应用,并提出一种适合于本体元模型的推理方法,并将该方法用于锻造工艺知识推理。本体元模型驱动的知识库构建方法在组织锻造知识时,具有构建速度快、良好的互操作和知识共享等优点。

| Abstract: | The key problem for a knowledge management system is the model of knowledge representation,which is the base stone of knowledge acquisition,sharing,reusing and deduction.The die forging knowledge was classified and summarized with the concept of domain ontology,and a die forging knowledge management model based on ontology meta-data model engine was proposed.Die forging knowledge domain ontology was set tentatively taking framework concept graph for representing the die forging knowledge.The application of ... |
