Abstract

The invention discloses an analysis method for a node relationship in an email network. The analysis method comprises the steps of: acquiring a directed graph corresponding to each node in a current network; determining a degree value of each node in a target network according to the corresponding directed graph, so as to obtain a metric matrix; carrying out screening processing on the nodes in the current network according to the degree values of the nodes in the metric matrix to obtain the target network; and calculating a pagerank value of each node in the target network, and completing theanalysis of the nodes in the current network. According to the analysis method, the degree values of the nodes are determined according to the directed graphs corresponding to the nodes in the current network, each node in the current network is subjected to screening analysis according to the degree value of each node, and a number of the nodes in the target network is reduced, thereby avoidingpagerank value calculation of isolated nodes in the current network or nodes having little association with the other nodes, and effectively reducing the calculation complexity and workload.

Description

technical field [0001] The invention relates to the technical field of network analysis, in particular to a method and system for analyzing node relationships in an e-mail network. Background technique [0002] Nowadays, with the rapid development of network technology, various networks emerge in endlessly. In order to optimize network resources, it is necessary to analyze each node contained in the network. Taking the e-mail network as an example, through the Analyze relationships and email sources to determine important nodes in the email network. [0003] Since there may be isolated nodes or nodes less associated with other nodes in the e-mail network, the above-mentioned nodes have little influence on the e-mail network, and the importance of the nodes may not be analyzed. Therefore, in the prior art, each node is analyzed The method leads to high computational complexity and heavy workload. Contents of the invention [0004] In view of this, the present invention pr...
