Embodiment Construction
[0053] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0054] figure 1 It is a schematic flowchart of a method for discovering social network communities based on improved density peak clustering provided by an embodiment of the present invention. like figure 1 As shown, the method includes steps S1 to S6.
[0055] S1. Collect the check-in data of all users in the social network, and initialize the community set C as an empty set;
[0056] S2. Based on the check-in data of all users, construct the user distance matrix D m×m , m is the number of users;
[0057] S3. Based on user distance matrix D m×m Calculate the cutoff distance d c ;
