Problems solved by technology
[0004] The above-mentioned network embedding methods are mostly suitable for stable and single static networks, such as static homogeneous information networks
However, for some dynamic networks with complex structures and frequent changes, such as dynamic heterogeneous information embedded networks, if the above network embedding method is used, when the nodes or the relationship between nodes in the network change, a new network needs to be rebuilt Embedding model, using the new network embedding model to embed the network, this embedding method takes a long time

Embodiments of the present invention provide a method, device, and electronic device for embedding a dynamic heterogeneous information network. The method includes: by obtaining the representation vector of the network at the previous moment and the variation of the representation vector, updating the representation vector of the network, and obtaining The representation vector of the network at the current moment, thus realizing the network embedding. In this scheme, since the representation vector of the network is updated by using the representation vector of the network at the last moment and the variation of the representation vector, it is not necessary to rebuild the network embedding model. Therefore, the embedding time is shortened.
Description
technical field [0001] The present invention relates to the field of network embedding, in particular to a method, device and electronic device for network embedding of dynamic heterogeneous information. Background technique [0002] A heterogeneous information network refers to an information network that includes multiple types of nodes or types of relationships between nodes. For example, the DBLP (DataBase systems and Logic Programming, integrated database system) academic network includes four types of nodes: authors, papers, conferences and keywords, as well as the writing / being written relationship between authors and papers, and between papers and conferences published / published relationship, etc. Heterogeneous information network embedding is the process of representing the nodes in the network and the relationship between nodes as vectors. In this process, it is necessary to ensure that the network structure and the relationship between nodes remain unchanged as m...
