Abstract

Embodiments of the present application disclose a text information processing method and device, which relate to the field of cloud computing. A specific implementation of the method includes: identifying the text to be processed from an image including the text to be processed; inputting the text to be processed into a pre-trained recurrent neural network language model to identify typos in the text to be processed; The typos are input into the pre-trained text error correction model, and the similar words corresponding to the typos are obtained; the text error correction model is used to determine the correct words corresponding to the typos in the similar words based on the coherence of the text to be processed, and the correct words are used to replace the typos, and get Error correction text for the text to be processed. The present application recognizes typos through a pre-trained recurrent neural network language model, and obtains the correct text of the typo through a pre-trained text error correction model, thereby obtaining error-corrected text and improving the accuracy of the recognition result.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technologies, and in particular, to a text information processing method and device. Background technique [0002] With the development of computer technology, OCR (Optical Character Recognition, Optical Character Recognition) character recognition technology is widely used in various fields. OCR text recognition technology can convert image information into text information, and then the machine uses natural language processing technology to perform semantic analysis and intent recognition on the text. [0003] At present, OCR text recognition technology is very mature for printed text recognition, and the accuracy can reach more than 90%. However, for handwritten text recognition, the existing OCR text recognition technology has low accuracy. [0004] In the prior art, the correction of the recognition result obtained by recognizing the handwritten text by the OCR technology ...
