In experiments using SVMs, the proposed method showed a higher NER Fmeasure, especially in terms of improving precision, than simply applying text-based NER to ASR results.
in text-based NER, better results are obtained using discriminative schemes such as maximum entropy (ME) models (Borthwick, 1999;Chieu and Ng, 2003), support vector machines (SVMs) (Isozaki and Kazawa, 2002), and conditional random fields (CRFs) (McCallum and Li, 2003).
