... 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 training ... 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 ... certain word representations are preferable for certain tasks. Lin and Wu (2009) finds that the representations that are good for NER are poor for search query classification, and vice-versa. We apply...
