Problems solved by technology

[0005] Therefore, although there are currently many graph databases that provide professional query tools and display interfaces, users are required to have professional graph database scripting capabilities and experience in using graph databases, and the use of graph databases cannot completely solve the problem of users in different business scenarios. specific functional requirements

Embodiment 1

[0041] see Figure 1-6 , the present invention provides a technical solution: a method for constructing a subgraph model for graph query, comprising the following steps:

[0042] S1. Create query: Create a sub-map query scene in the map preview module, determine the name of the sub-map query and select the map to be queried, for example, create a "transit sub-line query" and select the "bus route map" map;

[0043] Among them, the graph preview module is used to display the entities and relationships of the general graph and subgraphs on the graph exploration page of the system logged in to the computer browser, select some relationships and entities that need to be queried in the general graph, and output and display them in the subgraphs;

[0044]S2. Build a sub-graph model in the sub-graph creation module, where the sub-graph creation module is used to pick entities and relationships in the overall graph, and display them in the sub-graph area, and duplicate entities in the...

Abstract

The invention discloses a method for constructing a sub-graph model to carry out graph query, which comprises the following steps of: S1, creating query: creating a scene of a certain sub-graph query in a graph preview module, determining a name of the sub-graph query and selecting a graph needing to be queried; s2, constructing a sub-graph model in the sub-graph creation module; s3, running the sub-graph model in the sub-graph running module and obtaining a query result; and S33, checking a background result: outputting and displaying the result on a map exploration page of the system in two modes of a map relationship and a json format. According to the method, by supporting establishment of sub-graph query, a small-range regional relationship is selected in a complex large graph to query graph data, no additional background is needed to establish a new graph, other sub-graph query is not affected, query personnel do not need professional graph database script knowledge, and refinement, high efficiency and high efficiency can be met. And accurate positioning query is realized.

Description

technical field [0001] The invention relates to the technical field of graph databases, in particular to a method for constructing a subgraph model for graph query. Background technique [0002] With the rapid development of science and technology, important progress has been made in representation learning technology represented by deep learning, which can represent the semantic information of entities as dense low-dimensional real-valued vectors, and then efficiently calculate entities, relationships and The complex semantic association between them is of great significance to the construction, reasoning, integration and application of knowledge bases. A more effective way makes the network more intelligent and closer to human cognitive thinking. The foundation of knowledge graph technology is graph database. Thanks to the development of knowledge graph, graph database has also been developed by leaps and bounds. The database is a data management system based on points an...
