Significant prior work has proposed using topics as well as words in document classification, and many complex models have been developed to use a mix of different representations of words and topics. But how much do these different representations actually contribute to accuracy in document classification? We categorize existing document classification approaches into two axes: a syntactic/semantic/both axis that considers what kind of information the model uses and a word/topic/both axis that considers how that information is used. We conduct evaluation experiments using a uniform methodology to determine which classes of models are the most effective for the task of document classification. Surprisingly, our results show that there is little difference in overall classification performance between different classes of models on average across many datasets, and few methods outperform or produce sparser models than a basic word-based document classifier.
