Classification is the alignment of data or items in predefined labeled groups based on resemblances. Exponential progression amount of scientific documents leads to uncontrollable physical classification. Feature extraction is the crucial condition of automatic document classification. TF-IDF (term frequency-inverse document frequency) is frequently used to represent the text feature weight. This paper proposes a new yet simple feature weighting scheme by modifying TF-IDF formula. The experimental results show that the modified method improves the accuracy and other parameters.
