有效地使用可视化分析系统可能会给用户带来陡峭的学习曲线，特别是对于那些对使用工具或完成分析任务知之甚少的用户。随着时间的推移，用户如何处理陡峭的学习曲线？分析过程中是否存在特别有问题的方面？在本文中，我们通过使用CiteSpacea可视化分析工具在科学文献中寻找趋势和模式的综合研究来调查这些问题。特别是，我们分析了全球用户在14个月期间生成的日志中的数百万个交互事件。主要发现有：(1)确定了三个熟练程度水平，即1级：低熟练程度，2级：中等熟练程度，3级：高熟练程度；（ii）第3级的行为模式是由与系统更有参与性的互动产生的，涉及更广泛的事件，并以更长的状态转换路径为特征，而第1级和第2级的行为模式似乎侧重于学习如何使用工具。本研究有助于在现实环境中开发和评估视觉分析系统，并为交互式视觉分析过程的研究提供了有价值的补充。
Using visual analytic systems effectively may incur a steep learning curve for users, especially for those who have little prior knowledge of either using the tool or accomplishing analytic tasks. How do users deal with a steep learning curve over time? Are there particularly problematic aspects of an analytic process? In this article we investigate these questions through an integrative study of the use of CiteSpacea visual analytic tool for finding trends and patterns in scientific literature. In particular, we analyze millions of interactive events in logs generated by users worldwide over a 14-month period. The key findings are: (i) three levels of proficiency are identified, namely, level 1: low proficiency, level 2: intermediate proficiency, and level 3: high proficiency, and (ii) behavioral patterns at level 3 are resulted from a more engaging interaction with the system, involving a wider variety of events and being characterized by longer state transition paths, whereas behavioral patterns at levels 1 and 2 seem to focus on learning how to use the tool. This study contributes to the development and evaluation of visual analytic systems in realistic settings and provides a valuable addition to the study of interactive visual analytic processes.
