在这项研究中，我们探讨了使用日志文件作为一个窗口到超媒体导航的过程。虽然有越来越多的研究机构解决有关的理论和设计问题的开放式，非指令性的技术，如超媒体，相对较少的研究试图解释导航性能。66名本科生使用了一个多维的，基于计算机的信息亭，可以探索在一个非线性的方式来寻找信息，以响应两个信息检索任务（简单或复杂）之一。聚类分析用于生成从日志文件中捕获的导航数据导出的性能配置文件。集群内的性能配置文件的分析，结合外部验证标准，导致四种不同类型的导航性能（模型用户，幻想破灭的志愿者，功能探险家，网络制图师）的分类。这些特征是一致的信息检索分数和外部标准（自我效能感，感知效用和兴趣）。例如，那些似乎花时间学习信息亭布局的人也有最高的自我效能感，而那些使用帮助屏幕和观看最多电影的人的自我效能感最低。结果还表明，各种个人导航配置文件和类型的信息检索任务之间的相互作用。
In this study we explored the use of log files as a window into the process of hypermedia navigation. Although there is a growing body of research addressing theoretical and design issues related to open-ended, non-directive technologies such as hypermedia, relatively few studies have attempted to explain navigational performance. Sixty-six undergraduate students used a multidimensional, computer-based kiosk that could be explored in a nonlinear fashion to find information in response to one of two information-retrieval tasks (simple or complex). Cluster analysis was used to generate performance profiles derived from navigational data captured in log files. Analyses of within-cluster performance profiles, combined with external validation criteria, led to the classification of four different types of navigational performance (models users, disenchanted volunteers, feature explorers, and cyber cartographers). These characterizations were consistent with information-retrieval scores and the external criteria (self-efficacy, perceived utility, and interest). For example, individuals who appeared to take the time to learn the layout of the kiosk also had the highest self-efficacy, while those who used the help screen and watched the most movies had the lowest self-efficacy. Results also demonstrated an interaction between various individual navigational profiles and type of information-retrieval task.
