摘　　要：[目的/意义]探究多元属性任务类型及其分面属性对用户选择不同模态网络健康信息偏好的影响作用,进而为个性化健康信息搜索服务设计,特别是生成式AI技术环境下面向健康任务的个性化信息搜索服务,提供思考路径。[方法/过程]基于任务分面分类理论与模拟仿真工作任务,设计一项准实验,共招募64名参与者,收集3497条有效健康信息数据,采用Fisher精确概率检验分析了用户在执行不同类型健康任务时对单/多模态网络健康信息选择的差异,并采用Z检验进行事后比较分析。[结果/结论]研究发现,用户搜索网络健康信息时倾向选择少数几种单/多模态信息,选择行为具有较强收敛性;不同类型健康任务在文本信息、文本—语音信息、文本—图像信息、文本—图像—视频、文本—视频等单/多模态健康信息选择比例上有显著差异;基于分析结果,研究提出了关于健康任务类型—信息模态偏好初步理论模型。[Purpose/Signiffcant]This study explores the impact of multi-attribute task types and their faceted attributes on users’preferences for selecting different models of online health information.Furthermore,it provides a path for the design of personalized health information search,especially in the context of generative AI technology.[Method/Process]Based on the task-faceted classiffcation theory and simulated work tasks,a quasi-experiment was designed.A total of 64 participants were recruited,and 3497 pieces of valid health information were collected.The Fisher’s precision probability test was employed to analyze the differences in selecting single/multi-modal online health information among different types of tasks,and the Z-test was used for post-hoc analysis.[Result/Conclusion]The results show that users tend to select a limited number of single/multi-modal information when searching for online health information,with a strong convergence in their selection behavior.Different types of health tasks have signiffcant differences in the selection ratios of single/multi-modal health information,such as text-only,text-audio,text-image,text-image-video and text-video.Based on the results,the study further proposes a preliminary theoretical model of health task type-information modality preference.
