A generative adversarial error correction system for English writing

Key Points

The research aims to tackle the problem of over-correction in AI writing tools by developing a generative adversarial error correction system.
Developed a two-network system where one modifies sentences and the other evaluates the necessity of changes.
Evaluated performance on public datasets to compare against traditional rule-based error correction methods.
Achieved 89.5% correction accuracy, significantly surpassing traditional methods with 70.2%.
Maintained an over-correction rate of only 12.1%, much lower than general-purpose large models at 35.7%.

Abstract

This paper addresses the prevalent issue of 'over-correction' in current AI English writing tools -where correct personalised expressions are often misidentified as errors -by proposing an innovative adversarial generative error correction system.This system mimics the 'teacher-student interaction' mechanism: one network attempts to modify sentences, while another network judges the necessity of such modifications, thereby achieving more precise error correction.For instance, a system might incorrectly 'correct' a stylistically chosen active-voice sentence (e.g., 'our team analysed the data') into a passive construction ('the data was analysed by our team'), thereby altering the author's intended emphasis.Another common over-correction involves replacing a correctly used but less frequent disciplinary term with a more common, yet less precise, synonym.In public dataset evaluations, the system achieves an 89.5% correction accuracy -a significant improvement over traditional rule-based methods (approximately 70.2%) -while maintaining an over-correction rate of only 12.1%, substantially lower than that of a general-purpose large model (approximately 35.7%).This demonstrates the advantages of adversarial generation methods in understanding writing intent and context, providing an effective pathway for developing smarter, more human-like writing assistance tools.
