The component plane analysis method was used to investigate relevance among one group of medical subjects. A transaction log from a public health portal was employed for the study. The subjects from a health subject directory in the portal were extracted and traversal activities among these subjects were analyzed. The focus theme”weight control” was selected and the relevance judgments about the related subjects to weight control were made in the visual contexts of the subject component planes. The findings of this study can be used to optimize the medical subject directories, and understand users’ medical information seeking behavior.
