Effective presentation of ontological overlap of multiple conceptual models
提出用颜色高亮突出多个概念模型间的重叠概念，通过在线实验和眼动实验评估其认知效果，发现颜色高亮能提升领域理解但未必提高问题解决效率，且效果取决于重叠程度。
Conceptual models are used to help professionals understand complex information systems and solve problems during systems analysis and design. Because single model often do not represent all relevant information, typically multiple models are used in combination. To design effective combinations of models, we propose a systematic approach that uses color highlighting to foreground overlapping concepts between multiple models to help readers identify corresponding information between models. We conducted two empirical studies – an online experiment and an eye-tracking experiment – to evaluate the cognitive efficacy of this approach. Our findings suggest that color highlighting can somewhat improve participants’ domain understanding but not the efficiency of problem-solving. Findings from the eye-tracking study suggest that the use of color can have both beneficial and harmful effects, depending on the extent of overlap. • Color highlighting aids the perceptual integration and synchronization of overlap between multiple conceptual models. • Color highlighting can improve information integration processes, which in some cases aids problem-solving. • Color highlighting has both positive and negative effects when it comes to the information search processes.
