数据到文档生成中的挑战

Challenges in Data-to-Document Generation

Sam Wiseman, Stuart M. Shieber, Alexander M. Rush

摘要:

最近的神经模型已经显示出显着的进展问题上产生简短的描述性文本的条件下,少量的数据库记录。在这项工作中,我们提出了一个稍微困难的数据到文本生成任务,并调查如何有效地目前的方法是在这项任务上。特别是,我们引入了一个新的,大规模的数据记录与描述性文档配对的语料库,提出了一系列用于分析性能的提取评估方法,并使用当前的神经生成方法获得基线结果。实验表明,这些模型产生流畅的文本,但无法令人信服地近似人类生成的文档。此外,即使是模板化的基线在某些指标上也超过了这些神经模型的性能,尽管基于复制和重建的扩展带来了显着的改进。

英文摘要:

Recent neural models have shown significant progress on the problem of generating short descriptive texts conditioned on a small number of database records. In this work, we suggest a slightly more difficult data-to-text generation task, and investigate how effective current approaches are on this task. In particular, we introduce a new, large-scale corpus of data records paired with descriptive documents, propose a series of extractive evaluation methods for analyzing performance, and obtain baseline results using current neural generation methods. Experiments show that these models produce fluent text, but fail to convincingly approximate human-generated documents. Moreover, even templated baselines exceed the performance of these neural models on some metrics, though copy- and reconstruction-based extensions lead to noticeable improvements.
