We make a comparison for word-based and n-gram-based representations when they are combined with weighting factors, such as term frequency(TF), inverse document frequency(IDF) and inverse class frequency(ICF). Experiment on CNA news collection shows that bigram achieves performance close to that of statistical word-based representations, and weighting methods that combine TF, IDF and ICF achieve the best performance.
