Abstract: With substantial expansion in the volume of computerized information, document classification has become an emerging area of exploration in the research community. A defined methodology for this task is to apply machine learning methods. The traditional term frequency and inverse document frequency weighting approach considers only the statistical information. This paper introduces a new approach to weight a term by calculating the semantic similarity between the category label and the term. Also, the weight of a term comprises of its co-occurrence computation. Experiments were carried on the Reuters-21578 benchmark dataset. The results obtained specify that the proposed method outperforms the traditional method with kNN classifier.
