We have investigated the users cognitive process and behavior in exploratory search on the Web. Through the laboratory experiments with more than 200 participants, we have collected users exploratory search process data with different detailnessf such as think-aloud protocol, gaze, depth interview, questionnaire, search logs, and concept maps, and analyzed users exploratory search process according to different tasks, topics and users characteristics. We have also proposed a set of new analytical frameworks such as Lookzone, Web action categories, LinkDepth, taxonomies for knowledge changes and utilization, and the data collection and analysis tools such as Copatt, QT honey, viscmaps. The proposed methods were also applied to evaluate various exploratory search systems and system function design.
