论文摘要
赋予主角具有特定的个性对于写一个引人入胜的故事至关重要。在本文中，我们旨在控制主角的故事生成角色，即从领先的环境和角色描述中产生一个故事，主角应通过连贯的事件序列表现出指定的个性。考虑到通常在故事中隐含且稀疏的角色，我们提出了一个名为Conper的基于计划的生成模型，以明确地对角色与事件之间的关系进行建模。 Conper首先计划了主角行为的事件，这些事件是由指定角色通过预测一个目标句子来激励的，然后将情节计划为一系列关键字，并在预测的与角色相关的事件和常识知识的指导下，并最终产生了整个故事。自动和手动评估结果都表明，Conper胜过最先进的基线，即产生更连贯和人格控制的故事。
Endowing the protagonist with a specific personality is essential for writing an engaging story. In this paper, we aim to control the protagonist's persona in story generation, i.e., generating a story from a leading context and a persona description, where the protagonist should exhibit the specified personality through a coherent event sequence. Considering that personas are usually embodied implicitly and sparsely in stories, we propose a planning-based generation model named CONPER to explicitly model the relationship between personas and events. CONPER first plans events of the protagonist's behavior which are motivated by the specified persona through predicting one target sentence, then plans the plot as a sequence of keywords with the guidance of the predicted persona-related events and commonsense knowledge, and finally generates the whole story. Both automatic and manual evaluation results demonstrate that CONPER outperforms state-of-the-art baselines for generating more coherent and persona-controllable stories.
