Abstract

The invention discloses a key information extraction method and device, a storage medium and an electronic device.The method comprises the steps that image features, position features and text features of a text block are determined according to annotation information of the text block in a target document, the annotation information comprises image information corresponding to the text block, the position of the text block in the target document and the text content of the text block, and the text feature comprises a first character feature of each character in the text block; fusing the image features, the position features and the text features to obtain text block features corresponding to the text blocks; according to the text block features and the first character features, key information in the text blocks is extracted, and by adopting the technical scheme, the problems that the extraction effect on documents with complex structures and rich text content is poor and the like are solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for extracting key information, a storage medium and an electronic device. Background technique [0002] With the rapid development of information technology, people need to process a lot of documents every day, and it is repetitive, time-consuming and labor-intensive to extract information from these documents by manpower. Extracting the key information of documents is a very useful technology, which aims at extracting the main key information from complex unstructured text and expressing it in a structured way. Using document key information extraction technology can quickly and efficiently find key information of interest from documents, replacing inefficient manual search forms, thereby greatly improving work efficiency. [0003] At present, with the proposal and use of some key information extraction methods based on deep learning, it has effectively pr...
