Abstract

The invention discloses a knowledge graph construction method and device and computer storage equipment, and the method comprises the steps: firstly carrying out the knowledge extraction from a data source associated with a specific entity word, and obtaining a triple of the specific entity word; fusing the obtained triples of the specific entity words with existing triples in a concept map to obtain a fusion result; performing hyponymy reasoning on the obtained fusion result to obtain a reasoning result for expanding the triad of the specific entity word; further translating the expanded triples in the reasoning result by utilizing a knowledge generation engine to obtain a translation result; and finally, writing the obtained translation result into a storage service through a storage engine.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a large-scale knowledge map construction method, device and computer storage device. Background technique [0002] Knowledge map, also known as knowledge domain visualization or knowledge domain mapping map, is a series of different graphics showing the relationship between knowledge development process and structure, using visualization technology to describe knowledge resources and their carriers, mining, analyzing, constructing, drawing and Show knowledge and their interrelationships. Knowledge graphs can be applied to many application scenarios, such as information recommendation based on knowledge graphs in information recommendation systems, or classification based on knowledge graphs in the process of text classification. Therefore, in order to ensure the wide application of knowledge graphs, there are many research methods to realize the constructi...
