This section starts with the length of the path, and the traditional direct limit path length affects some long and effective paths.<br>In order to solve this problem, the concept of k-step shortest path and k-step shortest metapath is proposed, and then according to the dynamic fixed length nature of k-step shortest metapath, the definition of k-step pattern diagram based on this concept is proposed, k-step pattern map not only preserves the original characteristics of network mode, but also greatly reduces the huge disadvantages of network mode scale, can be used to locally replace the original network mode, solve the problem of lack of practicality of network mode in the model-rich heterogeneous information network.<br><br>After solving the above key problems, we designed the automatic mining algorithm of complex heterogeneic information network path based on intensive learning in section 5.
