Abstract

The invention provides a graph query method and device and a storage medium, and the method comprises the steps: obtaining a to-be-queried sub-graph; performing querying in an abstract graph corresponding to an original graph according to the to-be-queried sub-graph, wherein the original graph represents a graph containing graph information corresponding to a to-be-queried sub-graph, the originalgraph is obtained by connecting nodes with attribute relations through edges, the edges in the original graph are marked with the attribute relations between the two connected nodes, and the abstractgraph represents a graph obtained after node combination is conducted on the original graph; and according to the to-be-queried sub-graph and the target query sub-graph, performing query in the original graph of the target query sub-graph to obtain a graph query result. By implementing the method and the device, the increasingly large graph scale caused by current development along with the timescan be better adapted, the query efficiency is high, the accuracy of the returned result is high, and the requirement of quickly and efficiently querying the sub-graphs in massive graph data can be met.

Description

technical field [0001] The invention relates to the field of graph data management, in particular to a graph query method, device and storage medium. Background technique [0002] With the rapid development of the economy, a lot of huge and complex data are generated in various fields, such as network, social network and biological network, which makes querying these data and collecting the beneficial value of these data bring great challenges. As a data structure that often appears in the engineering field, a graph is composed of nodes and edges, and has many advantages such as clear logical relationships and resource optimization. [0003] With the development and popularization of information technology, data information in various fields has increased rapidly. In the context of big data with such a sharp increase in data size, people may only be interested in some of the information and tend to extract useful information for themselves. At this time, graph query is part...
