Social network user cognitive vulnerability analysis method and device based on fuzzy comprehensive evaluation technology

The invention discloses a social network user cognitive vulnerability analysis method and device based on a fuzzy comprehensive evaluation technology, and the method comprises the steps: constructing a cognitive vulnerability three-level evaluation index system, and obtaining the text content published by a user on a social network, respectively analyzing scores of three-level indexes corresponding to the personality dimension, the interest dimension and the emotion dimension of the user according to the text content; respectively determining weight coefficients corresponding to the second-level indexes and the third-level indexes by adopting an analytic hierarchy process; and performing cognitive vulnerability level fuzzification on the third-level indexes, determining membership functions corresponding to the third-level indexes, and calculating membership functions of cognitive vulnerability levels of the users by utilizing fuzzy comprehensive evaluation according to the membership functions and weight coe
