... instances. We compare the learning curve from Co-training with a baseline of majority class and an upper-bound, in which the classifiers are trained on human-annotated data. Post-hoc analyses ... generate more labeled data automatically. The main focus of this paper is to explore how Co- training can be applied to annotate spoken dialogues. A major challenge to address is in...
