Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings.
[0019] refer to Figure 1 ~ Figure 3 , a method for clustering analysis of scientific papers based on variational graph autoencoders and K-Means, including the following steps:
[0020] Step 1: Express the data of scientific papers to be analyzed as a citation network G=(V, E, F), where V={v 1 ,v 2 ,...,v n} is a collection of nodes, each node represents a scientific paper, the number of nodes is the total number of scientific papers n=|V|, E is a collection of edges, if there is a citation relationship between two papers, the corresponding nodes of the two papers There is an edge between them, and the edge relationship of all papers constitutes an n×n adjacency matrix A, and the keyword attribute of each paper is F={f 1 ,f 2 ,..., f m}, the number of attributes m=|F|, the attributes of all papers are expressed as an n×m attribute information characteristic matri...
