Abstract As most of website users use website category to access information, the similarity between the structure of category and the mental model of users will affect the efficiency of information access. The character of spatiality can disclose the latent psychology criterion of user’s appraisement of different concepts, it mean the relative position of user’s mental space . This paper focuses on access users’ cognition from web log data. We design the Multidimensional scaling (MDS) algorithm of spatial measure of user’s mental mode, and our method can offer new view for website user research. This paper reviews the research about website classification based on user cognition, including the future development of website category. Secondly, this paper elaborates mechanism of website users’ conceptual structure in the progress of information access. Then, this paper analyzes the application of research methods about mental model in the research of website users’ cognition. Finally, taking MIC for instance, design experiment based on mental model classification theory to analyze the relationship between users’ cognition and website category. The result can provide quantitative support for website category optimization.
