Abstract: Provided are method for recognizing a receipt, an electronic device and a storage medium, which relate to the fields of deep learning and pattern recognition. The method may include: a target receipt to be recognized is acquired; two-dimensional position information of multiple text blocks on the target receipt respectively is encoded, to obtain multiple encoding results; graph convolution is performed on the multiple encoding results respectively, to obtain multiple convolution results; and each of the multiple convolution results is recognized based on a first conditional random field model, to obtain a first prediction result at text block-level of the target receipt, wherein the first conditional random field model and a second conditional random field model are co-trained, so as to obtain a second prediction result at token-level of the target receipt.

Abstract: A method of processing a text, an electronic device, and a storage medium, which relates to a field of an image processing technology, in particular to a field of computer vision technology. The method includes: determining similarities between a plurality of fields contained in a text image to be processed and a plurality of predetermined field names; determining, from the plurality of fields, a field having a similarity greater than a similarity threshold as a target field name; determining a target field value corresponding to the target field name from M remaining field among the plurality of fields other than the target field name, where M≥1; and outputting a correspondence between the target field name and the target field value.
