Abstract

Text categorization is a task of automatically assigning documents to a set of predefined categories. Usually it involves a document representation method and term weighting scheme. This paper proposes a new term weighting scheme called Modified Inverse Document Frequency (MIDF) to improve the performance of text categorization. The document represented in MIDF is trained using the support vector machines classifier with radial basis function kernel. The experiments are carried out in Reuters-21578 corpora. The performance measures taken for text categorization are F1–measure and cost measure. The proposed term weighting scheme performs better than the existing term weighting schemes.
