Abstract

The embodiment of the invention provides a node similarity calculation method, device and equipment and a computer readable storage medium. The method comprises the steps of obtaining a bipartite graph, wherein the bipartite graph comprises nodes of a first type and nodes of a second type; according to the bipartite graph, determining a first set and a second set, connecting each node in the firstset with the first node of the first type, and connecting each node in the second set with the second node of the first type; according to the number of the same nodes in the first set and the secondset, the first weight value of the connection line between the first node and each node in the first set, the second weight value of the connection line between the second node and each node in the second set, and the similarity between each node in the first set and each node in the second set, determining the similarity between the first node and the second node. According to the embodiment ofthe invention, the accuracy of calculating the similarity between the low-weight distributed nodes is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a method, device, equipment, and computer-readable storage medium for calculating node similarity. Background technique [0002] Bipartite graph includes two types of nodes, among them, nodes of the same type are not connected, nodes of different types are connected, and the weights of the edges connected between nodes of different types are positive integers. For example, in an e-commerce scenario, the relationship between a user set and a product set can be abstracted into a bipartite graph. If a user has clicked on a product, there can be an edge connecting the user to the clicked product, and the number of clicks can be used as the weight of the edge; In the advertising scenario, the user has searched for and clicked on the advertisement, and the relationship between the user set and the advertisement set can be abstracted into a bipartite gra...
