Problems solved by technology
However, the inventors found in the research that since the distribution of nodes in the heterogeneous information network follows a power-law distribution, the Euclidean space does not have the characteristics of a power-law distribution. Therefore, when the heterogeneous information network is embedded in the Euclidean space, the heterogeneous information The structure of the network and the semantic information in it are not fully preserved, that is, the embedding accuracy is not high enough

The embodiment of the invention provides an embedding method and device for a heterogeneous information network. The method can comprise the following steps: determining a representation vector of each node in the heterogeneous information network to be embedded; Inputting the determined representation vector into a preset hyperbolic space embedding model; And based on the hyperbolic space embedding model, performing exponential mapping in the hyperbolic space on the representation vector to obtain an embedding vector of each node in the hyperbolic space. By applying the embodiment of the invention, the hyperbolic space and the heterogeneous information network also have power law distribution characteristics, so that the structure and semantic information of the heterogeneous informationnetwork can be embodied in the hyperbolic space in a better fitting manner, and the structure and semantic information of the heterogeneous information network are kept more complete. Therefore, the embedding accuracy can be improved.
Description
technical field [0001] The invention relates to the field of network embedding, in particular to a heterogeneous information network embedding method and device. Background technique [0002] The embedding of the heterogeneous information network refers to projecting the nodes and the relationship between the nodes in the heterogeneous information network into the metric space, and expressing the nodes and the relationship between the nodes as vectors in the metric space. Generally speaking, try to ensure the integrity of the structure of the original heterogeneous information network and the semantic information in it, that is, try to ensure that the relationship between nodes in the original heterogeneous information network remains unchanged. [0003] At present, most solutions are to embed heterogeneous information networks in Euclidean space, that is, Euclidean space. However, the inventors found in the research that since the distribution of nodes in the heterogeneous...
