Abstract

The invention discloses a text error correction method and device, and relates to the technical field of computers. One specific embodiment of the method comprises the steps of performing a first error correction operation on a to-be-corrected text obtained by image recognition to obtain a first error correction text of the to-be-corrected text, the first error correction operation comprising: performing character error correction on characters whose confidence does not meet a preset condition in the to-be-corrected text by using a candidate character set; and based on the text structure characteristics of the first error correction text, performing structured text restoration on the first error correction text to obtain a final error correction text, the text structure characteristics including one or more of complete attribute constraint conditions of the text items, value domain constraint conditions of the text items, and dependency existence constraint strips between the text items. According to the embodiment, the text recognition precision can be rapidly improved, text error correction is automatically carried out, error correction is carried out by fully utilizing text structuralization characteristics, the structuralization accuracy is improved, and then the accuracy of a service processing result is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a text error correction method and device. Background technique [0002] At present, the text used in many business scenarios is obtained through image recognition through OCR (Optical Character Recognition) and other technologies. Due to the uneven quality of the source image of the text, the accuracy of text recognition varies greatly, which affects the business. Accuracy of Processing Results. For example, the most important basis for an insurance company to underwrite an insurance policy is the data of the customer's medical examination report. Currently, most of the medical examination reports received by insurance companies are images of the medical examination report uploaded by customers or agents, which need to be processed by OCR technology. Carry out character recognition and structure, and then automatically identify risk factors through machine learning models to ...
