Most previous works on text categorization applied term occurrence frequency and inverse document frequency for representing importance of terms. This work presents an analysis of inverse class frequency in centroid-based text categorization. There are two aims of this paper. The first one is to find appropriate functions of inverse class frequency. The other is to find the key factors for using inverse class frequency. The experimental results show that the key factors, which improve… CONTINUE READING
