Matthews correlation coefficient is set as the best metric to train the word-level task.
Using the DCSQE framework, synthetic data is generated from the WMT2023 parallel corpus for pre-training, and then fine-tuned on the WMT2022 QE EN-DE training set, all implemented with the Fairseq framework.
For a detailed description of the DCSQE framework, please refer to the paper:
