DATA ANALYSIS METHOD AND APPARATUS, AND COMPUTER SYSTEM AND READABLE STORAGE MEDIUM

摘要

Disclosed are a data analysis method and apparatus, and a computer system and a readable storage medium, which are based on the field of big data. The method comprises: creating a directed graph used for describing an association relationship and an asset relationship between nodes, and calculating a risk conduction coefficient of each path in the directed graph by means of an infectious disease model, so as to obtain a scale-free model; identifying an infection node in the scale-free model, and calculating the risk conductivity of each path in the scale-free model according to the infection node in combination with the risk conduction coefficient, so as to obtain a risk infection model; and extracting a node in the risk infection model according to a node request sent by a user end, taking the node as a target node, and calculating the risk conductivity of the target node in an incoming direction and the risk conductivity thereof in an outgoing direction, so as to obtain an incoming risk rate and an outgoing risk rate. According to the present application, the technical effects of deep mining of information in a knowledge graph and providing deep and valuable information are achieved.
