Abstract

The invention belongs to the technical field of social media semantic analysis, and particularly relates to a social group cognitive index construction method based on social media. The invention provides a social group cognitive index construction method based on social media. The method comprises the following steps of: analyzing the difference between a non-social group cognitive feature themeand a social group cognitive feature; in different regions and different time periods, obtaining social group cognition expressive indexes based on social media and social group cognition initiative indexes based on social media respectively, and obtaining social group cognition indexes capable of being compared in different time periods and regions. The influence of individual subjective factorson data collection is eliminated, and social group cognitive status evaluation can be carried out more accurately. According to the method, the social cognition indexes are constructed at a multi-level level, so that the social group cognition data of local residents can be longitudinally acquired according to different regional characteristics, and the multi-dimensional comparison and evaluationof regional social group cognition can be realized.
