云制造資源語(yǔ)義發(fā)現(xiàn)關(guān)鍵技術(shù)研究
[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.
