Problems solved by technology

Most of the existing document processing technologies only perform Optical Character Recognition (OCR) processing on documents, and the layout information of documents is easily lost during processing, which is not conducive to the full-dimensional analysis and understanding of documents by machines.
Existing natural language processing mainly relies on elements such as semantics, and cannot realize metadata extraction and knowledge construction of documents, which is not conducive to the processing of downstream tasks, for example, not conducive to the construction of knowledge bases or knowledge networks

Abstract

The invention provides a cross-modal document processing method and device and electronic equipment. The method comprises the steps of obtaining text modal data and image modal data of a first document; converting the text modal data into a word and sentence feature embedding vector based on a natural language processing model, and extracting a first text element feature according to the text modal data; based on a computer vision algorithm, through a target detection algorithm and an optical character recognition algorithm, positioning a target position, recognizing text content of the firstdocument, extracting second text element features according to the image modal data, and performing element alignment to obtain structural features of the first document; and then obtaining a meta-knowledge graph model which comprises representation of the first document in combination with the structural features and the embedded representation of the multi-dimensional features of the document. Based on this, the text content of the document is converted into the meta-knowledge graph model, so that the electronic equipment can identify and understand the document content more completely by using the meta-knowledge graph model.

Description

technical field [0001] The present invention relates to the technical field of computer data processing, in particular to a cross-modal document processing method, device and electronic equipment. Background technique [0002] Documents are usually a file type formed by human natural language plus format information. Processing documents can enable machines to better use human data information. Most existing document processing technologies only perform Optical Character Recognition (OCR) processing on documents, and the format information of documents is easily lost during processing, which is not conducive to the full-dimensional analysis and understanding of documents by machines. Existing natural language processing mainly relies on elements such as semantics, and cannot realize metadata extraction and knowledge construction of documents, which is not conducive to the processing of downstream tasks, for example, it is not conducive to the construction of knowledge bases ...
