摘　　要：采用日志分析、问卷调查和访谈等方法,设计用户实验,每位受试者均对两个不同类型的探索式医学搜索任务进行搜索和学习,从日志和认知的角度综合比较分析探索式医学搜索行为的特点和规律。日志分析从起始阶段、搜索词、组面浏览次数和时长、链接深度、其他特点等方面展开;认知分析从认知负荷、认知影响因素、认知趋势特点、注意力分配情况、认知加工要素等方面展开。最后建立探索式医学搜索行为模型。Combined three methods of log analysis, questionnaire and interview, this article designs the exploratory medical search experiments, in which every participant searches and studies 2 different types of search tasks, and analyzes the characteristics and laws of exploratory medical search from perspectives of log and cognitive analysis. Log analysis explores from following aspects of the beginning phase, search term, number and length of browse in a phase, link depth and others. Cognitive analysis explores from following aspects of the cognitive load, cognitive factors, cognitive trend, concentration distribution, cognitive processing elements, etc. Finally, it establishes the exploratory medical search model.
