A Hierarchical Hybrid Neural Network Architecture for Chinese Text Summarization.

Using sequence-to-sequence models for abstractive text summarization is generally plagued by three problems: inability to deal with out-of-vocabulary words, repetition in summaries and time-consuming in training. The paper proposes a hierarchical hybrid neural network architecture for Chinese text summarization. Three mechanisms, hierarchical attention mechanism, pointer mechanism and coverage mechanism, are integrated into the architecture to improve the performance of summarization. The proposed model is applied to Chinese news headline generation. The experimental results suggest that the model outperforms the baseline in ROUGE scores and the three mechanisms can improve the quality of summaries.
