Abstract

The invention relates to the technical field of financial data analysis, and provides a risk early warning method based on a knowledge graph and a storage medium. The method comprises the steps that financial heterogeneous information is obtained to the maximum extent by using the convenience of big data, and multiple pieces of standardized structured data are obtained through unified information processing; a stock knowledge graph is established to understand relevance of each individual stock in each industry through the stock knowledge graph, so that data analysis is more comprehensive, and the accuracy of risk early warning is improved; then, for real-time changes of stock quotes, dynamic weights are calculated according to a dynamic weight algorithm, and a multi-factor risk control model corresponding to each industry is updated in real time, so that a risk sorting list is in a dynamically corrected state and closely follows change trends of stock transactions, and the accuracy of the risk early warning is further improved; and finally, personalized risk early warning is output for different users, so that the operation difficulty of the users can be reduced, and the actual requirements of the users are met.

Description

technical field [0001] The present invention relates to the technical field of financial data analysis, in particular to a risk warning method and a storage medium based on a knowledge graph. Background technique [0002] Knowledge Graph, known as knowledge domain visualization or knowledge domain mapping map in the library and information industry, is a series of different graphics showing the knowledge development process and structural relationship, using visualization technology to describe knowledge resources and their carriers, mining , analyze, construct, map and display knowledge and their interconnections. [0003] The knowledge map is a combination of theories and methods of applied mathematics, graphics, information visualization technology, information science and other disciplines with metrology citation analysis, co-occurrence analysis and other methods, and uses the visual map to vividly display the core structure and development of the discipline. History, f...
