CTRLsum: Towards Generic Controllable Text Summarization

He, Junxian, Kryściński, Wojciech, McCann, Bryan et al.

Understand

Current summarization systems yield generic summaries that are disconnected from users' preferences and expectations.

  • To address this limitation, we present CTRLsum, a novel framework for controllable summarization.
  • Our approach enables users to control multiple aspects of generated summaries by interacting with the summarization system through textual input in the form of a set of keywords or descriptive prompts.
  • Using a single unified model, CTRLsum is able to achieve a broad scope of summary manipulation at inference time without requiring additional human annotations or pre-defining a set of control aspects during training.
