基于集对分析的电子地图可用性评价研究

本文针对电子地图可用性中存在的不确定性,应用集对分析理论对电子地图可用性评价问题进行研究。在研究中首先介绍了集对分析理论的主要内容,然后描述了建立基于联系度的电子地图可用性评价模型的过程,最后以两幅电子地图为例,运用可用性评价模型进行了具体评价研究,以验证该方法的可行性。研究结果表明该方法不仅可以找出电子地图可用性方面存在的主要问题,而且可以对地图进行可用性排序,是一种有效而简便的可用性评价方法。

Usability evaluation of electronic maps based on set pair analysis

Usability evaluation is a new work in the cartography. But because the common usability methods can not solve the uncertainty in the use of electronic map perfectly, this paper applied Set Pair Analysis (SPA) theory in the usability evaluation of electronic maps in order to solve the problem. In this paper, the main contents of the SPA were introduced. And then it described the process of building the usability evaluation model of electronic map based on degree of connexion which is the main idea of the SPA. At last it applied the usability evaluation model in two electronic maps in order to validate the feasibility of usability evaluation method based on SPA. The results showed that the method not only can find the major problems of the usability in the electronic maps, but also can give the sequence of the maps according to the score of degree of connexion. So the method based on SPA is an effective and easy method of usability evaluation.
