Abstract

The embodiment of the invention is suitable for the technical field of data processing, and provides a data extraction method and device, terminal equipment and a storage medium, and the method comprises the steps: obtaining a to-be-processed document, carrying out the preprocessing of the to-be-processed document, and generating a target data set; performing regular matching on the target data set by adopting pre-generated document matching information, and extracting text data in the target data set; intercepting a table in the document to be processed; performing regular matching on text contents in the table by adopting the document matching information, and extracting table data in the to-be-processed document; and storing the text data and the table data. According to the embodimentof the invention, the text data and the table data are respectively processed, so that the problem that extraction errors easily occur when the text data and the table data are extracted according tothe same mode is solved, and the accuracy of data extraction is improved.

Description

technical field [0001] The present application belongs to the technical field of data processing, and in particular relates to a data extraction method, device, terminal equipment and storage medium. Background technique [0002] At present, investors obtain relevant information about listed companies mainly from the announcements of the three meetings issued by the company, namely the announcement of the board of directors, the announcement of the board of supervisors and the announcement of the general meeting of shareholders. If you want to use the detailed data in the announcement, you can only do it manually. The staff read the announcement text one by one, and then extract useful data to support the corresponding research. [0003] When a large number of announcements need to be processed, it is extremely inefficient to manually extract data from announcements. If the extracted data is the data in the form, when the staff enters the form data, it is also very prone to...
