【摘要】：随着互联网通道能力和运算能力的增强以及互联网整合技术和应用服务的演进，云计算作为一种新的互联网模式应运而生。以此为基础，制造领域出现的云制造模式使得制造企业获得所需资源的机会大大增加，加快了制造企业的信息化进程。在山西省自然科学基金项目《复杂互联网环境下的制造资源发现及企业应用集成方法研究》资助下，论文综合运用语义网、本体建模开发和搜索引擎的相关技术理论，对云制造资源语义发现的关键技术进行了研究。设计了云制造资源语义发现的总体框架。本文在分析了云制造资源的特点后，设计了云制造资源语义发现的总体框架。同时，，探讨了实现云制造资源语义发现的关键技术，从而为实现云制造的全球化奠定了基础。建立了基于云计算的制造资源本体库。制造资源的本体建模是规范云制造资源的基础。本文在对本体建模技术进行研究的基础上，提出了制造资源分类模型。以此为基础，对云制造资源进行了分析与建模，建立了初步的制造资源本体库。设计了制造领域本体映射的流程。统一规范没有歧义的制造资源是资源共享、资源发现和语义搜索等关键环节的基础。在分析了异构资源本体的特点后，结合本体概念相似度计算的方法，设计了制造领域本体映射的流程。在上述工作的基础上，基于搜索引擎技术构建了云制造资源语义搜索引擎系统Mris，探索性地实现了系统中的制造资源语义搜索服务。并用实验验证了该系统在语义搜索制造资源时的准确性和可行性。
[Abstract]:With the enhancement of Internet channel capacity and computing power, as well as the evolution of Internet integration technology and application services, cloud computing as a new Internet model came into being. On this basis, the cloud manufacturing model in manufacturing field greatly increases the opportunities for manufacturing enterprises to obtain the required resources, and speeds up the information process of manufacturing enterprises. Supported by Shanxi Natural Science Foundation project "Research on Manufacturing Resources Discovery and Enterprise Application Integration in complex Internet Environment", this paper synthetically uses semantic Web, Ontology Modeling and search engine technology theory. The key technologies of semantic discovery of cloud manufacturing resources are studied. An overall framework for semantic discovery of cloud manufacturing resources is designed. After analyzing the characteristics of cloud manufacturing resources, this paper designs an overall framework for semantic discovery of cloud manufacturing resources. At the same time, the key technologies to realize semantic discovery of cloud manufacturing resources are discussed, which lays a foundation for the globalization of cloud manufacturing. The manufacturing resource ontology library based on cloud computing is established. Ontology modeling of manufacturing resources is the basis of standardizing cloud manufacturing resources. Based on the research of ontology modeling technology, a classification model of manufacturing resources is proposed in this paper. On this basis, the cloud manufacturing resources are analyzed and modeled, and a preliminary ontology database of manufacturing resources is established. The process of manufacturing domain ontology mapping is designed. Uniform specification of manufacturing resources without ambiguity is the basis of resource sharing, resource discovery and semantic search. After analyzing the characteristics of heterogeneous resource ontology and combining the method of ontology concept similarity calculation, the mapping process of manufacturing domain ontology is designed. Based on the above work, a cloud manufacturing resource semantic search engine system (Mris,) is constructed based on search engine technology. The accuracy and feasibility of the system in semantic search of manufacturing resources are verified by experiments.
