Abstract

A method for intelligently checking financial documents, a deive and a storage medium are provided in the invention which relates information extraction tecnology. The method comprises: combining natural language processing with information extraction, in the aspect of paragraph text, through effective word segmentation, part-of-speech analysis, named entity recognition, dependency syntax analysisand semantic role analysis, the effect of text information extraction and paragraph text semantic understanding being greatly improved, and the unstructured text data being transformed into structured financial tuples. For tables, use python, the best parser for text tables Docx transforms the table into a data structure that can be processed by computer, then divides the table into regions according to the header information, understands the table semantics, accurately realizes the table element location and element extraction, and transforms the semi-structured table data into structured financial tuples; Finally, the parsed financial structured tuples can be checked with the data of financial statements, and also can be checked for context consistency.

Description

technical field [0001] The present invention relates to the technical field of information extraction, in particular to a financial document intelligent verification method, device and storage medium. Background technique [0002] A financial document is a type of text that contains large amounts of unstructured financial data, mainly consisting of text paragraphs and tabular data. Most financial document verification workers are doing repetitive and low-tech document verification work manually, and the work tasks are very heavy. Its verification content includes the correctness of financial data and the consistency of data / indicator context. Automatically realizing the intelligent verification of financial documents will reduce the business cost and work efficiency of financial institutions. Therefore, how to realize the intelligent verification of financial documents has become a problem that has attracted much attention and research in the industry. [0003] Financial d...
