A frequent word sequence method is proposed to search for the salient semantic information and has been integrated into the document profile model. The experimental study of taxonomy generation using hierarchical agglomerative clustering has shown a significant improvement in terms of Fscore based on the document profile model. A close examination reveals that the integration of semantic information has a clear contribution compared to the classic bag-of-words approach. This study encourages us to further investigate the possibility of applying document profile model over a wide range of text based mining tasks. © 2008 by IGI Global.||Source Title:||Emerging Technologies of Text Mining: Techniques and Applications||URI:||http://scholarbank.nus.edu.sg/handle/10635/86118||ISBN:||9781599043739||DOI:||10.4018/978-1-59904-373-9.ch005|
