Search is very important to acquire useful information from the Web. To provide better search service, we need to look into how people conduct search. In this paper, we focus on web search behavior, and try to identify how it relates to the personality traits, then investigate the potential personality predicting model based on search behaviors. Several features are extracted from web search behavior, corresponding personality-trait scores are obtained, too. Correlation analysis method is used to deal with the data, the results show that part of searching behaviors are correlated with personality traits in some degree.
