Abstract

The invention relates to the technical field of big data analysis, and provides a market risk monitoring method and system based on a knowledge graph, Internet transaction data is acquired by adopting a web crawler technology, and the data acquisition range is expanded by utilizing the advantages of big data, so that the accuracy of risk early warning is effectively improved; the price fluctuation amplitude is calculated according to the previous quotation, the previous transaction price, the today quotation and the today transaction price, and whether the current price fluctuation is abnormal or not can be judged more accurately by combining the previous transaction price with the current transaction price and referring to the price change on a certain time line; the multi-level response is realized by adopting a sectional early warning strategy, and when the current price fluctuation is abnormal, professionals can be quickly contacted to carry out risk assessment, so that market regulation and control can be carried out in time, the monitoring efficiency is high, and the monitoring cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of big data analysis, in particular to a market risk monitoring method and system based on a knowledge graph. Background technique [0002] Knowledge map, known as knowledge domain visualization or knowledge domain mapping map in the library and information industry, is a series of various graphs showing the development process and structural relationship of knowledge. , drawing and displaying knowledge and their interrelationships, knowledge graph is a combination of theories and methods of applied mathematics, graphics, information visualization technology, information science and other disciplines with quantitative citation analysis, co-occurrence analysis and other methods, And use the visual map to visualize the core structure, development history, frontier fields and overall knowledge structure of the modern theory and knowledge map for the purpose of multi-disciplinary integration, which can provide p...
