[Abstract]:In view of the traditional modular optimization community partition algorithm can only use the network structure information, but can not use the same rich content information, resulting in low division accuracy problem. A community partition algorithm CCSRW (Classification with Content-Structure and Random Walk) is proposed, which combines the content attributes and weights the connected edges to optimize the topology of the network. The similarity matrix between structure node and content node is calculated by random walk theory, and the structure node is mapped to content attribute space. Finally, the problem of community division is transformed into multi-dimensional unsupervised clustering problem. Through a comprehensive experimental analysis on real data sets, it is shown that compared with the traditional community partition algorithm, the proposed algorithm can describe the network structure more accurately, significantly improve the partition performance, and effectively solve the problem of small community insensitivity. More suitable for large-scale complex information network community division.
