In this paper, we propose an abstractive document summarization method by applying guidance signals of key sentences to the encoder based on the hierarchical encoder-decoder architecture, denoted as KI-HABS  ...  Finally, we adopt key information representation guided selective encoding strategies to filter source information, which establishes a connection between the key sentences and the document.  ...  Therefore, we construct a Key Information Guided Hierarchical Abstractive Summarization model (KI-HABS), and the framework of our model is shown in Fig. 2 .  ...
