Abstract

The invention relates to a data extraction method, a device, computer equipment and a readable storage medium. The data extraction method includes: segmenting to-be-processed data to obtain data sets;inputting the data sets into a preset neural network model to obtain initial extracted data and feature labels corresponding to the initial extracted data; extracting corresponding target extracted-data from the initial extracted data according to a preset rule template; and carrying out association output on the target extracted-data and feature labels corresponding to the target extracted-data.According to the above-mentioned data extraction method, no limit of an extraction rule exists when the different-format data are extracted, data extraction is carried out for mapping relationships of the data sets and the feature labels through custom extraction rules, an error rate in extracting the different-format data can be decreased, and an extraction effect is better.

Description

technical field [0001] The invention relates to the computer field, in particular to a data extraction method, device, computer equipment and readable storage medium. Background technique [0002] The rapid development of modern information technology and storage technology and the rapid spread of the Internet have enabled people to come into contact with various information on the Internet in their daily lives; in the era of big data, what people lack is not information, but the massive and complex Obtain useful information that people care about from information; the advantage of data extraction technology is that it simplifies the process of natural language processing, and only focuses on relevant information while ignoring irrelevant content. [0003] The traditional data extraction method is mainly through rule extraction, that is, to identify and locate the information elements of interest, and then customize the extraction rules according to linguistic features and r...
