摘要
以滚动轴承知识为对象 ,利用集成定义方法 (IDEF)的建模技术 ,借鉴产品模型数据交换标准 (STEP)应用协议的开发方法 ,对知识建模进行了系统的分析 ,建立了中性知识表征体系 ,并用人工神经网络、规则推理和人工参与相结合的方法实现了知识检索 ,突破了传统规则推理的缺陷 .同时 ,为支持产品分布式集成信息系统底层知识的建模和检索提供了系统方法 .
Taking rolling bearing as an object, based on IDEF (Integrated Definiton method) modeling technique and development method of STEP (STandard for the Exchange of Product model data) application protocol, a neutral knowledge modeling scheme is constructed. Combined with artificial neural networks, rule reasoning and man-machine conversation, a knowledge retrieving approach is proposed. It provides a systematic approach for knowledge modeling and retrieving for distributed integrated information system.
