面向服务聚合应用的地理信息服务质量评价
|
摘要
针对地理信息服务质量提升过程中的服务聚合评价问题,在现有服务质量评价模型基础上,考虑待聚合服务间的关联性,提出了主服务的概念,并在此之上构建了独立评价、关联评价等多类型评价指标体系,形成了以源服务数据质量、执行质量、成果质量、源服务与主服务的一致性、兼容性等评价指标的面向服务聚合应用的可扩展的地理信息服务质量评价模型。以天地图·四川为主服务,利用本文提出的地理信息服务质量评价模型,构建了在线地理信息服务质量评价系统,并对其中各评价指标的取值方案进行了探讨,分析与评价了该模型及指标的合理性,从而为地理信息服务聚合应用奠定了基础。
It is an important issue in face of researchers about how to aggregate diversified services and promote the utilization of information for large numbers of geospatial information service. In this paper, a flexible frame to evaluate the quality of geospatial information service based on the basic Quality of Service(Qo S) model was put forward. In this frame, lots of indexes to evaluate the Qos were proposed, such as the absolute evaluation index, relative evaluation index by the relationship between the services to be aggregated based on the qualities of data, process and result, the consistency and the compatibility. Taking the Map World Sichuan as the main service, a prototype system to evaluate the quality of geospatial information service was built. Furthermore, this study provided the detailed researches on the method for taking values of indexes and their weights. With the prototype system, the different qualities of service for Map World and other geospatial information services were calculated and compared with each other. The results indicate that it is an effective method to evaluate the Qo S with our frameand can be used as important references of geospatial information service aggregation.
