摘　　要：To deal with a lack of semantic interoperability of traditional knowledge retrieval approaches, a semantic-based networked manufacturing （NM） knowledge retrieval architecture is proposed, which offers a series of tools for supporting the sharing of knowledge and promoting NM collaboration. A 5-tuple based semantic information retrieval model is proposed, which includes the interoperation on the semantic layer, and a test process is given for this model. The recall ratio and the precision ratio of manufacturing knowledge retrieval are proved to be greatly improved by evaluation. Thus, a practical and reliable approach based on the semantic web is provided for solving the correlated concrete problems in regional networked manufacturing.针对传统知识检索方法缺少语义层次互操作的技术缺陷,建立了一个基于语义web的制造知识检索系统的体系结构.该结构包括一系列支持知识共享以促进网络化制造协同的机制.提出了一种基于五元组的语义信息检索模型,建立了一套语义网络化制造知识检索测试方法.最后,经过实例验证该系统能显著提高网络化制造模式下制造知识信息检索的准确率和查全率,为解决区域性网络化制造中的相关知识检索问题提供了一条切实可行的途径.
