Dialogue Intent Classification with Long Short-Term Memory Networks

Dialogue intent analysis plays an important role for dialogue systems. In this paper, we present a deep hierarchical LSTM model to classify the intent of a dialogue utterance. The model is able to recognize and classify user's dialogue intent in an efficient way. Moreover, we introduce a memory module to the hierarchical LSTM model, so that our model can utilize more context information to perform classification. We evaluate the two proposed models on a real-world conversational dataset from a Chinese famous e-commerce service. The experimental results show that our proposed model outperforms the baselines.
