a simple and general method for semisupervised learning

... semi-supervised learning approach that we use is that it is simpler and more general than that of Ando and Zhang (2005) and Suzuki and Isozaki (2008). Their methods dictate a particular choice of model and ... the final NER F1 results. We compare to the state-of-the-art methods of Ando and Zhang (2005), Suzuki and Isozaki (2008), and for NER—Lin and Wu (2009). Tables 2 and 3 show that accuracy can be ... improve generalization accuracy. Semi-supervised models such as Ando and Zhang (2005), Suzuki and Isozaki (2008), and Suzuki et al. (2009) achieve state-of-the-art accuracy. However, these approaches...
