Problems solved by technology

The current market product-related functions are relatively weak, and it is impossible to comprehensively measure the impact of changes in upstream and downstream related industries and risk events, and then predict industry trends and carry out risk warnings
[0003] At present, the main form of market products is based on risk index, and more attention is paid to changes in relevant indicators in the industry, such as total profit, main business income, number of employees, etc. , it is impossible to comprehensively measure the risk impact brought about by changes in related industries such as the real estate industry and the raw material industry
At the same time, most of the current market products cannot dynamically capture events and actively warn of industrial risks
In the cutting-edge field, there are already relevant mature cases for the construction of industrial chain knowledge graphs, but the combination with theoretical analysis is still an important shortcoming in practical applications
In the frontier field, the "Learning Tracks" of several factories, the "Euler Map" of Ping An Cloud, and the "iFinD" of Flush are all exploring and constructing knowledge maps of the industrial chain, and at the same time integrating event analysis to achieve dynamic deduction functions. There are still some problems in the application of the current industrial chain knowledge map that integrates event analysis, so there is an urgent need for a knowledge map that can accurately integrate event analysis

Embodiment 1

[0041] figure 1 A schematic diagram of a map construction process provided by an embodiment of the present invention, the process includes the following steps:

[0042] S101: For each industry chain, obtain the map text used to construct the industry chain; from the map text, obtain entity information and information about the relationship between entities; create corresponding nodes according to the obtained entity information , and connect the corresponding nodes according to the information of the association relationship between the entities to construct the knowledge map of the industrial chain.

[0043] The map construction process provided by the embodiments of the present invention is applied to electronic devices, which may be smart devices such as PCs, smart home devices, or servers, where the smart home devices may be, for example, smart refrigerators, smart TVs, and other devices.

[0044] In order to accurately construct an event graph, electronic devices store g...

Embodiment 2

[0053] In order to accurately construct an event map, on the basis of the above-mentioned embodiments, in the embodiment of the present invention, according to the association relationship between the entities corresponding to the pre-saved industry chain, the knowledge map that connects the constructed industry chain has The nodes corresponding to the entities of the connection relationship include:

[0054] According to the association relationship between the entities corresponding to the pre-saved industry chain, determine the knowledge graph of the industry chain corresponding to the entity with the association relationship;

[0055] According to the association relationship between the entities, the nodes corresponding to the corresponding entities in the determined knowledge map of the industrial chain are connected.

[0056] In order to accurately construct an event map, in the embodiment of the present invention, the electronic device stores the association relationsh...

Embodiment 3

[0069] In order to accurately construct the event map, on the basis of the above-mentioned embodiments, in the embodiment of the present invention, the event evolution law is constructed in the following manner:

[0070] Extracting the second event contained in the collected public opinion information, the third event corresponding to the cause, and the fourth event corresponding to the result;

[0071] If any of the third node corresponding to the second event, the fourth node corresponding to the third event, and the fifth node corresponding to the fourth event are not included in the intermediate event evolution law to be constructed, then create the corresponding node;

[0072] If the intermediate event evolution law does not include the connection relationship from the fourth node to the third node, or does not include the connection relationship from the third node to the fifth node, then establish the fourth node A connection relationship pointing to the third node, or...

Abstract

The embodiment of the invention provides an atlas construction method, an early warning method, equipment and a medium, which are used for accurately constructing an affair atlas. In the embodiment of the invention, the knowledge graph of each industrial chain is created for the industrial chain, and after the knowledge graph of each industrial chain is created, the created knowledge graphs are connected to form the intermediate knowledge graph, and the incidence relation between the intermediate knowledge graph and the event in the event evolution rule is accurately established, therefore, the event atlas can be accurately established in the embodiment of the invention.

Description

technical field [0001] The present invention relates to the technical field of knowledge graphs, in particular to a graph construction and early warning method, device and medium. Background technique [0002] With the development of society, home appliances have gradually become an indispensable part of life. However, in Qingdao alone, the annual output value of the home appliance industry chain is nearly 200 billion yuan, involving nearly one million employees, and nearly a thousand upstream and downstream supporting enterprises. Contributed more than 20 billion in taxes. At present, there are multi-dimensional risk factors such as market, technology, and policy, which need to be identified in a timely manner, and one event will affect the whole body. The current market product-related functions are relatively weak, and it is impossible to comprehensively measure the impact of changes in upstream and downstream related industries and risk events, and then predict industry...
