Abstract

The invention discloses a social network user influence prediction method based on a fused emotional tendency theme. An influence calculation result of an existing method is general, and the actual influence of a user cannot be effectively reflected. The method comprises the steps of firstly, extracting theme information with different emotional tendencies of the user, and establishing a corresponding user blog article information list; secondly, establishing a user-emotional tendency theme influence matrix, and obtaining emotional tendency theme similarity, neighbor similarity and user similarity information; and finally, establishing a prediction model, and carrying out influence prediction on the unobserved emotional tendency theme. According to the method, emotional tendency is fused,and behavior user attributes are combined, so that the value of influence measurement is more accurate, the influence degree of one user can be better reflected, the influence of the user on an unobserved theme can be predicted, the method is not limited to a theme observed by historical data of the user, but various similar information is fused; the problem of data sparseness is solved, and the prediction result is more accurate.
