Character-Based Text Classification using Top Down Semantic Model for Sentence Representation

29 May 2017 Zhenzhou Wu Xin Zheng Daniel Dahlmeier

Despite the success of deep learning on many fronts especially image and speech, its application in text classification often is still not as good as a simple linear SVM on n-gram TF-IDF representation especially for smaller datasets. Deep learning tends to emphasize on sentence level semantics when learning a representation with models like recurrent neural network or recursive neural network, however from the success of TF-IDF representation, it seems a bag-of-words type of representation has its strength...
