[Abstract]:With the rapid development of information technology and the integration of three networks, the Internet, telecommunications network and radio and television network services are speeding up integration, which has produced massive data resources in different network platforms. The existing digital library can not support such a huge data business processing, and it is difficult for users to obtain personalized book resources. The traditional library information service has been greatly challenged. In order to solve the above problems, this paper applies cloud computing technology to the construction of cloud service platform of digital resources under the condition of digital library and three-network convergence. This paper puts forward the architecture of digital resource cloud service platform and the mode of providing digital resources under the combination of three networks, which can provide the integrated services of personalized digital resources, platform resources and management services resources for the users and libraries in the region. It lays a foundation for the construction of regional digital library under the environment of three networks integration. The main work of this paper is as follows: (1) the architecture of digital resource cloud service platform under the environment of three-network convergence is proposed. The platform architecture includes digital resource providing layer, IaaS layer, PaaS layer, SaaS layer, integrated network layer, user service layer, and so on. The distributed digital book resources in the environment of three-network convergence can be integrated across libraries to form an adaptive cloud platform of digital resources, and the digital resources can be provided to the users under the three-network convergence with Widget services. The platform architecture can support heterogeneous networks and heterogeneous terminal scenarios. (2) using the domain ontology of digital resource cloud services to establish a preference tree, the book user model and resource cloud service model under the environment of three-network convergence are constructed. The model includes preference and resource context. According to the functional requirements of the users under the three-network convergence, a personalized recommendation method based on the functional attributes of the resource cloud services is proposed to provide personalized digital resource cloud services for the users under the three-network convergence. (3) based on the definition of OWL_S_QoS, a personalized recommendation method is proposed. A user context ontology and a resource cloud service context ontology are proposed, which can support the hybrid data types to describe the dynamic and uncertain QoS preferences in a three-network convergence environment, and according to the non-functional requirements of the users under the three-network convergence environment. A service selection method based on the non-functional attributes of resource cloud services is proposed. The collaborative filtering algorithm is used to provide personalized digital resource cloud services for users under the three-network convergence.
