SummAE: Zero-Shot Abstractive Text Summarization using Length-Agnostic Auto-Encoders

Liu, Peter J., Chung, Yu-An, Ren, Jie

Understand

We propose an end-to-end neural model for zero-shot abstractive text summarization of paragraphs, and introduce a benchmark task, ROCSumm, based on ROCStories, a subset for which we collected human summaries.

  • In this task, five-sentence stories (paragraphs) are summarized with one sentence, using human summaries only for evaluation.
  • We show results for extractive and human baselines to demonstrate a large abstractive gap in performance.
  • Our model, SummAE, consists of a denoising auto-encoder that embeds sentences and paragraphs in a common space, from which either can be decoded.
