The chain-structured long shortterm memory (LSTM) has been shown to be effective in a wide range of tasks such as language modeling, machine translation and speech recognition. Because it cannot storage the structure of hierarchical information language, we extend it to a tree-structure based recursive neural network to capture more syntactic and semantic information, as well as the sentiment polarity shifting. Compared to LSTM, RNN etc, the proposed model achieves a state-of-the-art performance.
