Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] figure 1 It is an application environment diagram of the text key information extraction method provided in one embodiment, such as figure 1 As shown, in this application environment, a terminal 110 and a server 120 are included. When it is necessary to extract key information such as the repayment date in the credit card bill text message received in the terminal, the terminal 110 sends the received credit card bill text message to the server 120, and the server 120 uses the received credit card bill text message as the text key information to be extracted Execute the text key information...

Abstract

The invention relates to a text key information extraction method and device, computer equipment and a storage medium. The method includes: obtaining a current text of the key information to be extracted; performing word segmentation processing on the current text to obtain a target word corresponding to the current text; obtaining each target word vector corresponding to the target word, and combining the corresponding target word vectors in the order of the current text according to the target words, to obtain a target vector matrix. The target vector matrix is processed according to the trained target neural network model, and the target position corresponding to the key information to be extracted is obtained. Among them, the target neural network model performs feature extraction in units of target word vectors. The feature extraction direction of the target neural network model is consistent with the order of the target word vectors in the target vector matrix; the target word corresponding to the target position is extracted from the current text as key information. The above method improves the accuracy of extracting key information.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a text key information extraction method, device, computer equipment and storage medium. Background technique [0002] With the development of information technology, the amount of information generated by daily activities is increasing. Therefore, there is a need to extract information in many scenarios. Alert users when a date is approaching. [0003] In the traditional technology, according to the information form is fixed, the position to extract the information is set, and when the information is received, the data is extracted from the information according to the set position. However, the forms of information are becoming more and more diverse at present, and the information obtained according to the preset position is not accurate. Contents of the invention [0004] Based on this, it is necessary to provide a text key information extraction method, device, computer...
