中文摘要：

图书馆云信息服务等级协议（ISLA）通过量化参数以客观地测量服务的质量。综合云QoS参数管理的形式及典型的SLA参数，结合DigiQUAL＋TM的研究方法，参考QoS的4个审视角度，以环境质量、交互质量与感知质量维度为研究对象，构建图书馆云服务质量概念模型，并通过实证来检验与修正概念模型。研究结果发现，服务透明度、资源安全、响应速度、服务时间、共享性、合作性、责任管理和保障管理是ISLA的关键参数指标；图书馆云服务中资源的安全性、服务的保障性对图书馆云用户使用图书馆云服务起着关键性的作用。

英文摘要：

The quality of service can be measured by quantification parameter in Information Service Level Agreement in library cloud computing service. In the study of quantification parameters in the information service, this paper takes environmental quality, interactive quality and perceived quality as the research object, constructs the concept model of library cloud computing service quality based on the SLA management method existing in cloud computing QoS parameter management, typical SLA parameters, the theory of DigiQUAL ＋ TM, and the four survey aspects of QoS, and then verifies and revises conceptual model by survey data. The results show that the ＂transparency of service＂, ＂safety of information ~source＂, ＂the speed of response＂, ＂the hours of service＂, ＂performance of sharing＂, ＂performance of cooperation＂, ＂ responsibility management＂, ＂accident protection management＂ are the key parameter indicators; The safety of resources and guarantee of information service are the biggest influencing factors in the library cloud computing service.
