An adaptive
spectral clustering method of extracting a network node
community attribute is disclosed. The method comprises the following steps of 1, setting the number of nodes in a mobile group intelligence
perception network to be M and defining
modularity of one
community formed by the M nodes to be Qmax, wherein an initialized
community number N equals to 1, a community attribute of a marked node v is Cv and the Qmax equals to 0; 2, acquiring a
similarity matrix through an intimacy vector of the node v relative to the whole M nodes; 3, arranging characteristic values of the
similarity matrix from large to small, clustering characteristic vector spaces constructed by the first N characteristic values and marking a community attribute of each node; 4, using the community attributes of all the clustered nodes to calculate the
modularity Q, if the Q is greater than or equal to Qmax, making the Qmax equal to the Q and making an optimum community classification number
Nop equal to the N, otherwise, directing entering into step 5; 5, making N equal to N+1; 6, repeating step3 to step5 till that the N equals to the M, the
Nop value is the optimum community classification number and the nodes in the community possess the optimum community attribute. By using the method, accuracy of the network node community classification can be increased.
