METHOD AND SYSTEM FOR RECOGNIZING CERTIFICATE ON BASIS OF GRAPH NEURAL NETWORK

A method and system for recognizing a certificate on the basis of a graph neural network. The method comprises: obtaining an image to be recognized (310); detecting content text comprised in the image to be recognized, and determining multiple bounding boxes (320); constructing a layout on the basis of the multiple bounding boxes (330), wherein the layout comprises a plurality of nodes and a plurality of edges, each node corresponds to a bounding box, and each edge correspond to the spatial position relationship between a bounding box and another bounding box; and processing the layout using a trained graph neural network model to determine field categories in the bounding boxes in the layout (340), and performing text recognition on key fields, so as to extract key information in the certificate.
