Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0050] In addition, if there are descriptions involving "first", "second"...

Abstract

The invention discloses a method for constructing industrial knowledge map based on industrial chain, which relates to the technical field of knowledge map in artificial intelligence. Firstly, the industrial chain is modeled, and then the industrial knowledge map is constructed according to the constructed industrial chain model. The industry knowledge map based on the industry chain established by the technical proposal of the embodiment of the invention can clearly reflect the entity-relation-entity and ' entity-eroperties-attribute value ' between the industry chains and within the industrychains, can facilitate financial researchers to further use knowledge mapping to study industrial chain conduction and event driving to find important events, to analyze information emotion and so on; The construction of industry knowledge map based on industry chain can effectively reduce the problem of excessive noise in the process of industry knowledge extraction, and the cold start problem of knowledge extraction can be avoided by using feature thesaurus to construct entity relationship.The embodiment scheme can realize incremental knowledge learning and effectively reduce the dependenceon professional researchers.

Description

technical field [0001] The invention relates to the technical field of knowledge graphs in artificial intelligence, in particular to a method for constructing industry knowledge graphs based on an industrial chain. Background technique [0002] Macro, industry and company research is the cornerstone of financial investing. However, with the development of the Internet and the explosive growth of massive macro, industry, and company information and data, the means to understand big data are limited, which limits the precise and fine analysis of these data and greatly reduces the potential value of big data. Therefore, intelligent analysis of big data is an urgent technical problem in the financial field. [0003] Knowledge Graph, with its powerful semantic processing ability and open organization ability, provides a strong background knowledge support for economic and financial research, and can effectively empower public opinion analysis, business insight, business intellig...
