Are Pre-trained Language Models Useful for Model Ensemble in Chinese Grammatical Error Correction?

1 code implementation24 May 2023 Chenming Tang, Xiuyu Wu, Yunfang Wu

To this end, we explore several ensemble strategies based on strong PLMs with four sophisticated single models.

An Error-Guided Correction Model for Chinese Spelling Error Correction

1 code implementation16 Jan 2023 Rui Sun, Xiuyu Wu, Yunfang Wu

By borrowing the powerful ability of BERT, we propose a novel zero-shot error detection method to do a preliminary detection, which guides our model to attend more on the probably wrong tokens in encoding and to avoid modifying the correct tokens in generating.

From Spelling to Grammar: A New Framework for Chinese Grammatical Error Correction

no code implementations3 Nov 2022 Xiuyu Wu, Yunfang Wu

To handle grammatical error correction, we design part-of-speech (POS) features and semantic class features to enhance the neural network model, and propose an auxiliary task to predict the POS sequence of the target sentence.

A Soft Label Strategy for Target-Level Sentiment Classification

no code implementations WS 2019 Da Yin, Xiao Liu, Xiuyu Wu, Baobao Chang

In this paper, we propose a soft label approach to target-level sentiment classification task, in which a history-based soft labeling model is proposed to measure the possibility of a context word as an opinion word.
