鉴于模式丰富的复杂异质信息网络上的网络模式的规模巨大，且可用性低，直接

In view of the large scale and low availability of the network model on the complex heterogeneous information network with rich patterns, it is necessary to <br>directly search for all length-limited meta-paths to the target node type from a given initial node type on the heterogeneous information network, and Through the merging operation layer by layer, a hierarchical pattern diagram is obtained.

Given the scale and low availability of network patterns on complex heterogeneic information networks with rich patterns,<br>Search directly on the heterogeneity information network for all metapaths with length limits to reach the target node type from a given initial node type, and get a hierarchical pattern diagram by merging operations layer by layer.
