TVStoryGen:一个用于生成具有人物描述的故事的数据集

TVStoryGen: A Dataset for Generating Stories with Character Descriptions

摘要:

我们介绍TVStoryGen,一个故事生成数据集,需要从一个简短的摘要和一组描述所涉及的人物的文档中生成详细的电视节目情节摘要。与其他故事生成数据集不同,TVStoryGen包含由专业编剧创作的故事,并且具有多个角色之间的复杂互动。在TVStoryGen中生成故事需要根据简短的摘要从提供的关于角色的冗长文档中提取相关信息。此外,我们建议在我们的数据集上训练逆向模型,以评估生成的故事的忠实性。我们从粉丝贡献的网站创建TVStoryGen,这使我们能够收集26k的剧集摘要,平均使用1868.7个代币。从经验上讲,我们采取分层故事生成方法,发现使用Oracle内容选择器进行角色描述的神经模型在自动度量上表现出最佳性能,显示了我们的数据集激发未来关于限制故事生成的研究的潜力。定性分析表明,表现最好的模式有时会产生不忠实于简短摘要的内容,这为未来的工作提出了有希望的方向。

英文摘要:

We introduce TVStoryGen, a story generation dataset that requires generating detailed TV show episode recaps from a brief summary and a set of documents describing the characters involved. Unlike other story generation datasets, TVStoryGen contains stories that are authored by professional screen-writers and that feature complex interactions among multiple characters. Generating stories in TVStoryGen requires drawing relevant information from the lengthy provided documents about characters based on the brief summary. In addition, we propose to train reverse models on our dataset for evaluating the faithfulness of generated stories. We create TVStoryGen from fan-contributed websites, which allows us to collect 26k episode recaps with 1868.7 tokens on average. Empirically, we take a hierarchical story generation approach and find that the neural model that uses oracle content selectors for character descriptions demonstrates the best performance on automatic metrics, showing the potential of our dataset to inspire future research on story generation with constraints. Qualitative analysis shows that the best-performing model sometimes generates content that is unfaithful to the short summaries, suggesting promising directions for future work.
