发布时间：2018-11-15 12:37
【摘要】：随着信息技术和三网融合的迅速发展,互联网、电信网和广播电视网业务正在加速融合,在不同网络平台中产生了海量的数据资源,现有数字图书馆无法支撑如此庞大的数据业务处理,并且用户很难获取到个性化的图书资源,传统的图书信息服务方式受到很大挑战。为了解决上述问题,本文从数字图书馆、三网融合的现状出发,将云计算技术应用到三网融合下数字资源云服务平台建设中,提出三网融合下数字资源云服务平台架构和数字资源提供方式,能够为区域内用户和图书馆提供个性化数字资源、平台资源、管理服务资源为一体的综合性服务,为三网融合环境下区域数字图书馆建设奠定基础。本文主要工作如下:(1)提出三网融合环境下数字资源云服务平台架构,该平台架构包括数字资源提供层、IaaS层、PaaS层、SaaS层、融合网络层、用户服务层,能将三网融合环境下的分布式数字图书资源跨库整合,形成一个自适应的数字资源云平台,并将数字资源以Widget服务提供给三网融合下的用户,该平台架构能够支撑异构网络和异构终端场景。(2)利用数字资源云服务领域本体建立偏好树,构建了三网融合环境下的图书用户模型和资源云服务模型,模型包括偏好和资源上下文。并根据三网融合下用户的功能性需求,提出基于资源云服务功能属性的个性化推荐方法,为三网融合下的用户提供个性化数字资源云服务。(3)在OWL_S_QoS+定义的基础上,提出用户上下文本体和资源云服务上下文本体,能够支撑混合数据类型描述三网融合环境下动态不确定的QoS偏好,并根据三网融合下用户的非功能性需求,提出基于资源云服务非功能属性的服务选择方法,该方法利用协同过滤算法为三网融合下的用户提供个性化数字资源云服务。
[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.
