| With the development of information technology and triple-play, the business of the Internet, telecommunication network and broadcast television network is accelerated integration with each other. In the different network platform, it creates a lot of digital education resources. However, the existing digital library cannot support bulk data handling and it’s also hard for user to obtain personalized library resources. To solve the problem, from the present research situation of cloud computing and triple-play in digital library, we apply the cloud computing to the construction of digital resource cloud platform and the service way of digital resource, which can provide comprehensive services to users and libraries, and it can lay the foundation for constructing the regional digital library in triple-play. The main work in this thesis is organized as follows:(1) A cloud services architecture of digital resource based on cloud computing technology in triple-play was put forward, which can integrate distributed digital library resources as a whole and built an adaptive cloud platform of digital resource, and it can present the cloud service in the form of Widget. The platform can support heterogeneous network and heterogeneous terminals.(2) By establishing preference tree with domain ontology, we have constructed user model and resource services model based on cloud computing in triple-play, which include preferences and resource context. Meanwhile, a personalized recommendation method based on functional attributes of service was presented, which can provide user with personalized digital resource services.(3) Based on OWL_S_QoS+, we presented user context ontology and service context ontology which can support describing the uncertain QoS in triple-play. Meanwhile, a service selection method based on non-functional attributes of service was presented, which can provide user with personalized digital resource services based on collaborative filtering. |
