Automatic data expansion and relation mining method and system

The invention provides a data automatic expansion and relation mining method. The method comprises the following steps: acquiring various information of nodes connected with resources; dynamically acquiring resource table information based on a database of the resource node, and further importing a field information list corresponding to the resource table; further creating and setting a resource table mapping model; calling a scene analysis module to obtain and store specific object data information; and rendering the resource nodes according to the obtained object data information and displaying the rendered resource nodes on an analysis board. By combining the analysis scene and the resource table mapping model, the technical practicability is higher, the applicable scene is wider, and the analysis is more flexible; according to a node graph operation function provided by the analysis board, a relation graph is more intuitive and concise; according to the method and the device, different resource tables ca
