基于用户偏好的多维地理信息服务质量评价模型

摘要

为了解决目前地理信息服务质量量化评价的问题,构建了一种基于用户偏好的多维地理信息服务质量评价模型.扩展通用服务质量属性,构建了多维地理信息服务质量模型；在多维地理信息服务质量模型的基础上加入用户偏好,构建了基于用户偏好的多维地理信息服务质量评价模型；实现了基于用户偏好的QoS权重计算,并给出了服务QoS综合值的计算方法.最后给出了基于用户偏好的多维地理信息服务质量评价实例.%In order to solve the problems of geographical information service QoS evaluation, multi-QoS model of geographical information service based on user preference was built. Common service QoS properties were extended to build multi-QoS model. User preference was imported based on multi-QoS model, and multi-QoS model of geographical information service based on user preference was built. Weight calculation of QoS based on user preference was realized, and the way of service QoS general value calculation was given. At last, a QoS evaluation example by the model was given.
