Problems solved by technology

Data mapping is a difficult point in user operation and use in the process of building knowledge graphs. The reason is that when performing data mapping, even for a very simple ontology model, it is necessary to create many mapping data (tables), and one mapping data is a mapping relationship. The expression of the mapping data, and the establishment of the mapping data is to manually input the corresponding data to form a piece of data. The more attributes involved in the mapping data, the greater the input volume. A piece of mapping data is performed on an independent page, and users need to repeatedly operate on different pages when creating different mapping data, making the user experience very poor
Moreover, the mapping data is directly stored in the server database. Every time a piece of mapping data is constructed, a data saving request is sent to the server, which makes the processing pressure on the server high and the cost is high.

Embodiment 1

[0047] see figure 1 , the data mapping method for knowledge graph construction provided in this embodiment includes the steps:

[0048] S10, monitor the event that the user completes the following operations in sequence on the same page: a selection operation on a node or edge in the ontology model, and a drag-and-drop operation on a field in the node table or edge table.

[0049] The ontology model includes nodes and edges, and edges represent the relationship between nodes, such as Figure 2a , Figure 2b shown.

[0050] The node table is used to import the node data in the graph. Each type of node is established as a node table. The type of the node is the type of the entity. One type of entity is one type of node. The mapping table corresponding to the node can be viewed differently. For different types of nodes, for example, the table vertex_person that records personal information corresponds to a node whose node type is human, and the table vertex_accout that records...

Embodiment 2

[0063] see image 3 , the data mapping method for knowledge graph construction provided in this embodiment includes the steps:

[0064] S100, monitor the event of the user's selection operation on the ontology model on a page, and if the occurrence of the event is monitored, the ontology model selected by the user is displayed on the page.

[0065] E.g Figure 2a shown, will Figure 2a The page shown in is divided into 4 areas, one area is represented by a solid line box. From left to right, define the first solid box on the left as area 1, the upper solid frame as area 2, the lower left solid frame as area 3, and the lower right solid frame as area 4. like Figure 2d As shown, in area 3, a search text box is displayed, through which the desired ontology model can be selected. After selection, the selected ontology model will be displayed in this area. easy to understand, Figure 2a The shown page is only a schematic presentation, and the method does not limit the speci...

Abstract

The present invention relates to a data mapping method and system for building a knowledge map, and an electronic device. The method includes the steps of: monitoring the event that the user completes the following operations in sequence on the same page: operations on nodes or edges in the ontology model, Operations on the fields in the node table or edge table; if an event is detected that the user completes the above operations on the same page, a mapping relationship between nodes and node tables, or a mapping relationship between edge tables is established. This solution can solve the problems of improving data mapping processing efficiency, improving user experience, and reducing server computing load at the same time.

Description

technical field [0001] The present invention relates to the technical field of knowledge graphs, in particular to a data mapping method, system and electronic device for building 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 various graphs showing the knowledge development process and structural relationship. , analyze, construct, map and display knowledge and the interconnections between them. As a representative technology of knowledge representation, knowledge graph describes concepts, entities, events and their interrelationships in the objective world, and has become an important way to construct data-information-knowledge. [0003] The construction of knowledge graph mainly includes several steps: data access, ontology modeling, data mapping, and graph generation. Data mapping is to convert the source data...
