When evaluating personality traits, both researchers and participants always find themselves annoyed by the questionnaires and surveys, and the answers may vary according to different degrees of the participant's carefulness. In this paper, we propose a novel and operable solution to make personality evaluations based on the lifelog data using a logistic regression model. It is the first time, to the best of our knowledge, that a new way is discovered of Big Five personality evaluation by using proactive and objective lifelog data, which is available for the large-scale user analyses. Impressive results have been achieved which shows the effectiveness of the proposed novel and easy-applicable idea with simple model.
