Mobile social network resource discovering method based on interest hotspots

The invention discloses a mobile social network resource discovering method based on interest hotspots. The method comprises the steps of: 1, carrying out effective expression of interest of nodes, and clustering the nodes according to the interest of the nodes, thereby forming interest hotspots; 2, carrying out effective expression of interest hotspots, and recording the migration change laws of the hotspots; 3, calculating social relationship among the nodes by using the access tracks of nodes to the hotspots; 4, for the nodes that share interest, searching resources according to the shared interest of the nodes and the constructed hotspots and 5, for the nodes that do not share interest, searching the resources by using the social relationship among the nodes. The searching process also comprises a step of constructing Markov prediction on the migration change of the hotspots, therefore, the searching efficiency and accuracy of the resources are improved, and the system overhead is reduced.
