before_sent:  Last but not the least, the attention-aware inference could be adopted to single-document summarization with straightforward modifications according to the model architecture .
before_sent_with_intent: <style>  Last but not the least, the attention-aware inference could be adopted to single-document summarization with straightforward modifications according to the model architecture .
after_sent:  Last but not the least, the attention-aware inference has strong universality that can be easily adopted to different hierarchical summarization models to promote the models' performance .
