The invention discloses a group-oriented service recommendation list generation method, which comprises the following steps of: generating a user relationship directed graph according to a relationship of users in a group; selecting p centroid users in the group, dividing the group into p subgroups according to the centroid users, and establishing a hierarchical grouping model for each subgroup; constructing a recommendation service set rating matrix of each subgroup, and calculating a recommendation weight of each subgroup to the to-be-recommended service set; and calculating an aggregation index of each service to be recommended according to the recommendation service set rating matrixes and the recommendation weights of all the subgroups, and carrying out ascending arrangement on all the services according to the aggregation indexes to obtain a service recommendation list. According to the service recommendation list obtained through the method, the user satisfaction degree of service recommendation can be improved, and the user-user satisfaction degree can be improved, and high-quality group recommendation service experience can be realized by taking mutual relation among user,group and project as center. Group And the mutual relation among the projects is taken as a center, so that higher-quality group recommendation service experience can be realized.
