Abstract

The invention provides a text error correction method and system. The text error correction method comprises the following steps: acquiring a to-be-processed text sequence, and inputting the to-be-processed text sequence into an editing operation word list to obtain a character sequence; inputting the character sequence into a text editing model to obtain a target editing prediction sequence corresponding to the to-be-processed text sequence; combining the to-be-processed text sequence and the target editing prediction sequence to form a target text sequence, wherein the text editing model is obtained by training according to a preset target editing sequence obtained by matching the to-be-processed text sequence with an editing operation word list. Through inputting a character sequence obtained by processing the to-be-processed text sequence into the text editing model, the target editing prediction sequence is obtained; the to-be-processed text sequence and the target editing prediction sequence are combined to form the target text sequence; the problem that text detection and error correction are uncontrollable is solved.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to a text error correction method and system. Background technique [0002] As the number of non-native language learners, writers, and users around the world continues to grow, the need for automated language assessment such as text error correction is also increasing. Among them, the automatic error correction of the text needs to automatically correct many errors in the original text, including grammar, spelling, content, etc., on the premise of maintaining the semantics of the original text. [0003] Existing technologies for automatic error correction of text include: inputting erroneous text into an encoder-decoder-based sequence-to-sequence model framework for error correction, and outputting the target text; that is, between sequences in the same language to map between. [0004] Defects or deficiencies in the prior art include: when the sequence-to-seq...
