Software supply chain security domain question and answer method based on large model and knowledge graph

Abstract

The invention relates to the field of software supply chain security, and provides a software supply chain security domain question and answer method based on a large model and a knowledge graph, which comprises the following steps: searching keywords in the software supply chain security domain to obtain a target website containing related articles; analyzing a page structure of the target website, and capturing text data through a crawler technology; the captured text data is cleaned and preprocessed; extracting triple information from the cleaned text data T'by using named entity recognition and relation extraction technologies, carrying out data processing on the extracted triple information, constructing a software supply chain security knowledge graph, and storing the software supply chain security knowledge graph in a graph database, and solving the technical problems of low accuracy and solution rate of software supply chain security questions and answers in the prior art.
