A method and a system for extracting individual share announcement data

Abstract

The invention discloses a method for extracting individual share announcement data, which is based on a universal framework and comprises the following steps of: carrying out preprocessing operation on a received individual share announcement by utilizing the universal framework to obtain a structured text file; Setting a data extraction rule according to the received configuration file; And carrying out data extraction on the structured text file by utilizing the universal framework according to the data extraction rule. The invention provides a general framework for extracting individual share announcement data. based on the universal framework, a data extraction rule is set for each type of individual share announcement in a configuration file; The data extraction is completed by the universal framework according to the configuration file, so that a user can set a data extraction rule in the configuration file according to the expected extraction information to complete the purposeof data extraction, and the burden of program developers is greatly reduced. The invention further provides a system and equipment for extracting the individual share announcement data and a computerreadable storage medium which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of data extraction, in particular to a method, system, device and computer-readable storage medium for extracting individual stock announcement data. Background technique [0002] Stock announcements are the most authoritative and timely information display window for listed companies, and their content is likely to have an important impact on investors' judgment of the company's fundamentals. Stock announcements often include all kinds of accurate and objective data information, important time periods and time node information, and the progress, operation, and preconditions for implementation of many matters. [0003] For investors, it is particularly important to quickly and accurately obtain the information in individual stock announcements.

Problems solved by technology

[0003] For investors, it is particularly important to quickly and accurately obtain the information in individual stock announcements. With the development of Internet technology, the amount of information on the Internet is growing explosively, and the number of individual stock announcements is too large. Reading is difficult to complete the acquisition of all individual stock announcement information. Based on this, in the prior art, information is extracted based on expectations, and corresponding extraction scripts are written for different types of individual stock announcements to extract information in various individual stock announcements.

[0004] However, due to the large number of categories of individual stock announcements, for program developers, it is necessary to write corresponding extraction scripts for each category, which makes program development less efficient and places a greater burden on program developers
