From the literature there are three term ranking methods to summarize term weights of different categories for multi-class text categorization. They are Summation, Average, and Maximum methods. In this paper we present a new term ranking method to summarize term weights, i.e. Maximum Gap. Using two different methods of information gain and χ2 statistic, we setup controlled experiments for different term ranking methods. Reuter-21578 text corpus is used as the dataset. Two popular classification algorithms SVM and Boostexter are adopted to evaluate the performance of different term ranking methods. Experimental results show that the new term ranking method performs better. © 2010 Springer-Verlag.]]> Wed 07 Apr 2021 13:34:53 AEST ]]> Profiling phishing emails based on hyperlink information http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:3795 Wed 07 Apr 2021 13:34:50 AEST ]]> Using links to aid web classification http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:3631 Wed 07 Apr 2021 13:34:38 AEST ]]> A formula for multiple classifiers in data mining based on Brandt semigroups http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:1781 Wed 07 Apr 2021 13:32:51 AEST ]]> Attribute weighted Naive Bayes classifier using a local optimization http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:5114 Mon 15 May 2023 11:16:23 AEST ]]>
