... requires some annotated words in the target domain. In this paper, we do not assume any predefined rules and labeled data be available in the target domain. 2.2 Domain Adaptation Domain adaptation aims at ... per- formance of a weak classifier by iteratively adding training data and retraining the classifier. More specifically, bootstrapping starts with a small set of labeled “seeds”, and ite...

... Work Discourse segmentation has been an active area of research (Hearst, 1994; Utiyama and Isahara, 2001; Galley et al., 2003; Malioutov and Barzilay, 2006). Our work extends the Bayesian segmenta- tion model ... construct a non- parametric Bayesian model for joint segmenta- tion and alignment of parallel parts. In com- parison with the discussed pipeline approaches, our method has two im...
