cloud service description is the foundation of cloud service composition in cloud manufacturing paradigm. Through unified encapsulation and description, cloud services in cloud manufacturing service platform can provide effective cloud service information for cloud service composition. This paper puts forward the requirements of cloud service description and modeling in cloud manufacturing paradigm. Based on the general ontology construction method, the core ontology and extensible ontology of cloud manufacturing service are constructed by extending OWL-S. On this basis, a formal description model of cloud manufacturing service is established, which supports the implementation of cloud service description method based on OWL-S for cloud service composition.
