Outline to Story: Fine-grained Controllable Story Generation from Cascaded Events

Understand

Large-scale pretrained language models have shown thrilling generation capabilities, especially when they generate consistent long text in thousands of words with ease.

• However, users of these models can only control the prefix of sentences or certain global aspects of generated text.
• It is challenging to simultaneously achieve fine-grained controllability and preserve the state-of-the-art unconditional text generation capability.
• In this paper, we first propose a new task named "Outline to Story" (O2S) as a test bed for fine-grained controllable generation of long text, which generates a multi-paragraph story from cascaded events, i.e.
