Incorporating hierarchy into text encoder

WebDue to the limitation of text encoding length by the popular encoders (e.g., BERT), existing studies [5–7] usually cut a long document into segments, and then take each segment as the input. This will lead to the macro discourse structure and generation model can not be fully utilized.
