Abstract

The embodiment of the invention relates to the technical field of big data, and particularly discloses a link prediction method and device and a storage medium, and the method comprises the steps: obtaining any node pair to be subjected to link prediction in a specified network, and taking the node pair as a target node pair; extracting common neighbor sharing influence, common neighbor dispersion influence and inter-node influence of the target node pair, wherein the common neighbor sharing influence is represented by the degree of the common neighbor node of the target node pair, the common neighbor dispersion influence is represented by the shortest path number of the common neighbor nodes of the target node pair, and the inter-node influence is represented by the similarity of common neighbor nodes of the target node pair; and performing link prediction on the target node pair according to the common neighbor sharing influence, the common neighbor dispersion influence and the inter-node influence of the target node pair so as to determine the link relationship between the node pairs in the specified network based on a link prediction result, thereby improving the accuracy and stability of network link prediction.

Description

technical field [0001] This specification relates to the technical field of big data, and in particular, relates to a link prediction method, device and storage medium. Background technique [0002] The goal of link prediction is to predict whether there is a link between each node pair in the network based on information such as past network nodes and network structure. Link prediction is a data mining problem that appears in many research fields. Social network friend recommendation is the most typical application of link prediction algorithms. If users are regarded as nodes in a social network, the friendship between users is a network node. Links, the influence indicators between node pairs are also the influence indicators among friends. [0003] The most efficient algorithm for solving the link prediction problem is the scoring method. In the scoring method, multiple scoring functions are defined that measure the similarity between network nodes. For each link in th...
