Abstract

The invention relates to an ICT supply chain key node identification method combining network topology and commercial attributes, and belongs to the field of natural language processing and machine learning. The method is mainly used for solving the problem that the criticality of ICT supply chain network nodes is influenced by the commercial attributes of the nodes and the topological structure in the network. The method comprises the following steps: firstly, embedding sentences by utilizing doc2vec to obtain vector representations of ICT supply chain network supplier node company types, registration states, residences and operation ranges, normalizing registration capital, and splicing vectors of the four commercial attributes and normalized values of the registration capital to obtaina sentence vector S1 fusing the five commercial attributes; secondly, obtaining an ICT supply chain network node topology embedding vector S2 by using a Deepwalk algorithm; and finally, splicing the vectors S1 and S2, and realizing ICT supply chain network key node identification through linear classification. An experiment is carried out on a supplier node information data set of an ICT supply chain network, a result shows that the method can achieve a better classification effect, and the accuracy reaches 71.4%.

Description

technical field [0001] The invention relates to a method for identifying key nodes of an ICT supply chain in combination with network topology and business attributes, and belongs to the fields of natural language processing and machine learning. Background technique [0002] With the popularization and application of Information & Communication Technology (ICT) in party and government departments and key industries, it is crucial to strengthen the security and controllability of the supply chain of ICT products and services. The ICT supply chain has the characteristics of global distribution and supplier diversity. The topological relationship of the supply chain network is more complicated, and the management and control are more difficult. Therefore, it is necessary to analyze and clarify the key nodes in the ICT supply chain network, and carry out targeted security management and guidance to effectively promote the security risk management and control of the ICT supply c...
