The method is characterized by comprising the steps: rearranging user groups which are divided aiming at respective concerned objects of all users in a social network, so as to obtain all user groups in the social network; selecting a user group for each preset interest category, and enabling the selected user group to serve as an interest core group corresponding to the related interest category; calculating the similarity between the other user groups and each selected interest core group, and enabling the user groups with similarity higher than a set threshold value to serve as a generalized interest group of the related interest core group; determining an interest mining result for each user in the social network according to the interest categories corresponding to the generalized interest group containing the related user. By applying the method, the accuracy of interest mining can be improved.
