NCTU and NTUT’s Entry to CLP-2014 Chinese Spelling Check Evaluation
Yih‐Ru Wang, Yuan‐Fu Liao · 2014
This paper describes our Chinese spelling check system submitted to SIGHAN Bake-off 2014 evaluation.The system's main components are still the conditional random field (CRF)-based word segmentation/part-ofspeech (POS) tagger and tri-gram language model (LM) used last year.But we tried to refine the misspelling rules, decision-making threshold and improve LM rescoring speed to reduce false alarm rate and improve rescoring speed.Bake-off 2014 evaluation results show that one of our system (Run2) did achieve reasonable performance with about 0.485/0.468accuracies and 0.226/0.180F1 scores in the detection/correction metrics.
