Abstract

The invention provides a data fusion method and device for a knowledge graph. The system for executing the method comprises a data platform configured with a unified access interface, and the method comprises the following steps: processing data from different data sources, converting the processed data into a triple format, storing the processed data into the data platform through the unified access interface, and receiving graph data index information returned by the data platform; according to the graph data index information, dividing an entity stored in the data platform into one or moresub-partitions according to attributes; performing similarity calculation on the candidate entity pairs divided into the same sub-partition, and screening out matched entity pairs meeting a preset similarity condition; and supplementing and / or replacing the entity attribute values of the matched entity pairs to generate a unified entity representation. By means of the method, the problem that an existing data fusion technology cannot flexibly adapt to data fusion of different knowledge bases can be effectively solved.

Description

technical field [0001] The present application relates to the technical field of knowledge graphs, in particular, to a method and device for data fusion of knowledge graphs. Background technique [0002] A knowledge graph is a huge semantic network graph that describes various entities or concepts and their relationships that exist in the real world. Its nodes represent entities or concepts, and its edges are composed of attributes or relationships. The current knowledge graph has been used to refer to various large-scale knowledge bases. Among them: entity refers to something that is distinguishable and exists independently, such as a certain country, a certain company, a certain person, etc. Attributes refer to the inherent characteristics of an entity. For example, a country has different attributes such as "population" and "area" (such as Figure 4 As shown), the company has attributes such as "name" and "legal representative". A relationship is an association between ...
