AbstractUnderstanding short texts is crucial to many applications, but it has always been challenging, due to the sparsity and ambiguity of information in short texts. In addition, sentiments expressed in those user-generated short texts are often implicit and context dependent. To address this, we propose a novel model based on two-level attention networks to identify the sentiment of short text. Our model first adopts attention mechanism to capture both local features and long-distance dependent features simultaneously, so that it is more robust against irrelevant information. Then the attention-based features are non-linearly combined with a bidirectional recurrent attention network, which enhances the expressive power of our model and automatically captures more relevant feature combinations. We evaluate the performance of our model on MR, SST-1 and SST-2 datasets. The experimental results show that our model can outperform the previous methods.
