Dynamic social network community evolution analysis method and system

The invention relates to a dynamic social network community evolution analysis method and system thereof, belongs to the technical field of network identification, and solves the problems that networktopology structure information cannot be fully utilized and types of core nodes are not distinguished in the prior art. The method comprises the following steps of: for a given dynamic social network, dividing a community structure corresponding to a time slice network for each time slice from a first time slice; calculating a superloader set of each time slice network and a superloader set of each community corresponding to the time slice network according to a community structure division result; determining an evolution event 1 type of each community for the superloader set, i.e., generating, merging and expanding events; and for the superblock set, determining the evolution event type 2 of each community, namely disappearing, splitting and reducing events. According to the method, thecharacteristics of high d
