Researchers from Yonsei University developed RTSUM, an unsupervised, interpretable summarization framework that extracts salient relation triples from text and transforms them into fluent summaries. The framework provides multi-level salience visualization, allowing users to understand content selection at the sentence, relation, and phrase levels.

Key insights

  • Combining fine-grained extractive units (relation triples) with abstractive generation offers a robust hybrid approach to summarization, balancing precision and fluency.
  • Multi-level salience scoring, incorporating sentence, relation triple, and phrase importance, provides a comprehensive understanding of textual significance for information selection.
  • Self-supervised training with careful data filtering can effectively teach a language model to "sentencify" structured information, circumventing the need for expensive human-annotated summaries.
