Abstract

The invention provides a method and device for exporting data in an image database. The method comprises the steps of: querying cells of to-be-exported data in an image database, wherein the cells comprise attribute names and label information of the to-be-exported data; under the condition that the label information is matched with preset label information, determining attribute IDs and attribute values of the to-be-exported data from the cells, and updating the attribute values to corresponding attribute names in a mapping table based on a mapping relation in the mapping table, wherein the mapping relation used for representing the attribute names and the attribute IDs of the to-be-exported data is pre-stored in the mapping table; exporting the to-be-exported data based on the mapping table. By means of the method and device, the problem that in the prior art, data are returned to an image database end from bottom storage and then returned to be exported from the image database, and consequently, the data exporting efficiency is low, is solved.

Description

technical field [0001] The present application relates to the technical field of knowledge graphs, in particular to a data export method and device in a graph database. Background technique [0002] The knowledge graph is used to describe the relationship between things. A specific description of the knowledge graph includes defining the entities in the graph (that is, the points in the graph), the relationships (that is, the edges in the graph) and the attributes related to entities / relationships ( That is, the property graph), whose description and definition are inseparable from the use of the graph database. The current common practice is to import the original data of the real entity relationship into the graph database, and then realize the construction of the knowledge graph through the interface of the graph database. [0003] The construction of knowledge graphs relies on graph databases. Currently, commonly used graph databases include Janusgraph, Hugegraph, Neo4j,...
