Abstract

The embodiment of the invention discloses a text information processing method and device, and relates to the field of cloud computing. A specific embodiment of the method comprises the steps of identifying a to-be-processed text from an image comprising the to-be-processed text; inputting the to-be-processed text into a pre-trained recurrent neural network language model, and identifying wronglywritten characters in the to-be-processed text; inputting the wrongly written characters in the to-be-processed text into a pre-trained text error correction model to obtain similar characters corresponding to the wrongly written characters; and determining correct characters corresponding to the wrongly written characters in the similar characters by utilizing the text error correction model based on the coherence of the to-be-processed text, and replacing the wrongly written characters with the correct characters to obtain an error correction text of the to-be-processed text. The wrongly written characters are recognized through the pre-trained recurrent neural network language model, and the correct characters of the wrongly written characters are obtained through the pre-trained text error correction model, so that the error correction text is obtained, and the accuracy of a recognition result is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, 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 performs semantic analysis and intention recognition on the text through natural language processing technology. [0003] At present, the OCR character recognition technology is very mature for printed text recognition, and the accuracy can reach more than 90%. However, for the recognition of handwritten text, the existing OCR character recognition technology has low accuracy. [0004] In the prior art, the correction of the recognition result obtained by recognizing the handwritten text ...
