【摘要】：随着云计算技术的逐渐成熟，网络信息资源的传播与共享变得更加快速便捷，但由于对网络信息资源的传播和发布缺乏严格的审核机制，使得大量低质量、不实信息充斥其中。因此，对已有网络信息资源的质量进行分析评价，使高质量资源能为用户所使用，是提高网络信息资源使用效率的关键。本文首先分析了云计算技术的发展现状，总结了网络信息资源评价的相关理论和常用方法。在综合分析现有评价标准与各评价方法优缺点的基础上，将网络信息资源评价方法运用于网络教育资源评价中，结合德尔菲法、层次分析法和模糊综合评价法，构建了一套网络教育资源综合评价模型。通过该模型建立了对网络教育资源定性评价、定量评价、反馈评价，三个维度的评价指标体系，，并为相关指标分配了权重值。最后，本文搭建了一个以OpenStack云计算平台为基础的教育资源共享系统，并将建立的网络教育资源评价模型应用于该平台之上，实现了对平台教育资源的综合评价功能。其评价结果客观、准确，达到了预期的目标。
[Abstract]:With the maturity of cloud computing technology, the dissemination and sharing of network information resources become more rapid and convenient. However, due to the lack of strict audit mechanism for the dissemination and distribution of network information resources, a large number of low quality, Therefore, it is the key to improve the efficiency of the use of network information resources to analyze and evaluate the quality of existing network information resources so that high quality resources can be used by users. This paper first analyzes the development of cloud computing technology, summarizes the relevant theories and common methods of network information resource evaluation, on the basis of comprehensive analysis of the existing evaluation standards and the advantages and disadvantages of each evaluation method, The evaluation method of network information resources is applied to the evaluation of network education resources, combined with Delphi method, analytic hierarchy process and fuzzy comprehensive evaluation method. In this paper, a comprehensive evaluation model of network education resources is established, through which the evaluation index system of qualitative evaluation, quantitative evaluation, feedback evaluation and three dimensions of evaluation index system are established, and the weights are assigned to the related indicators. Finally, this paper builds an educational resource sharing system based on OpenStack cloud computing platform, and applies the network education resource evaluation model to this platform. The comprehensive evaluation function of platform educational resources is realized, and the evaluation results are objective, accurate and achieve the expected goal.
