Problems solved by technology
However, the current knowledge graph is updated in real time, so it is difficult to trace the historical graph
[0004] The Chinese invention patent application with the publication number CN110580293A discloses a method and device for storing entity relationships, which can solve the technical problem of being unable to query historical entity relationships by storing entity relationships before and after changes
However, this method can only query the entity relationship. The entity relationship is only a small part of the data in the knowledge graph and is independent of other data. This method still cannot solve the technical problem of how to trace the historical graph

The invention relates to a multi-version knowledge graph storage method and device, a storage medium and electronic equipment. The multi-version knowledge graph storage method comprises the followingsteps that a main version graph updated in real time is generated, and the main version graph is updated along with updating of a data source linked with the main version graph; and at least one sub-version graph with update time solidified is generated, the solidification time of the sub-version graph is the update cutting time of a data source linked with the sub-version graph. According to themulti-version knowledge graph storage method, the main version graph capable of being updated in real time and the at least one sub-version graph belonging to the historical version are provided, generation of multiple versions of the knowledge graph is achieved, and real-time updating and history tracing are facilitated. Therefore, compared with an existing graph platform / product, the multi-version knowledge graph storage method has the advantages that the historical graph can be traced on the basis of updating the graph in real time, and better applicability is achieved.
Description
technical field [0001] The present invention relates to the technical field of knowledge graphs, in particular to a storage method, device, storage medium and electronic equipment for multi-version knowledge graphs. Background technique [0002] Knowledge graph (Knowledge Graph), known as knowledge domain visualization or knowledge domain mapping map in the library and information industry, is a series of different graphics showing the knowledge development process and structural relationship, using visualization technology to describe knowledge resources and their carriers, mining , analyze, construct, map and display knowledge and their interconnections. [0003] At present, the research and development of knowledge graphs focuses on how to better visualize data and how to implement more powerful graph computing methods. For this reason, many visual graph layouts with standard definitions have emerged, such as hierarchical layout, gravity layout, grid layout, etc. , Pager...
