TGSum: Build Tweet Guided Multi-Document Summarization Dataset

Understand

The development of summarization research has been significantly hampered by the costly acquisition of reference summaries.

• This paper proposes an effective way to automatically collect large scales of news-related multi-document summaries with reference to social media's reactions.
• We utilize two types of social labels in tweets, i.e., hashtags and hyper-links.
• Hashtags are used to cluster documents into different topic sets.
