摘要:

我们提出了DART,一个开放域结构的数据记录到文本生成数据集,超过82 k个实例(DART)。Data-to-Text注释可能是一个代价高昂的过程,特别是在处理结构化数据的主要来源和包含重要结构的表时。为此,我们提出了一个过程中提取语义三元组的表,编码其结构,利用表标题和表标题之间的语义依赖关系。我们的数据集构建框架有效地合并异构源开放域语义解析和基于对话行为的意义表示任务,利用技术,如:树本体注释,问答对陈述句转换,谓词统一,所有最小的后期编辑。我们对DART进行了系统的评估,并在WebNLG 2017上展示了最新的最先进的结果,以表明DART(1)对现有的数据到文本数据集提出了新的挑战,(2)促进了领域泛化。我们的数据和代码可以在https://github.com/Yale-LILY/dart上找到。

英文摘要:

We present DART, an open domain structured DAta Record to Text generation dataset with over 82k instances (DARTs). Data-to-Text annotations can be a costly process, especially when dealing with tables which are the major source of structured data and contain nontrivial structures. To this end, we propose a procedure of extracting semantic triples from tables that encodes their structures by exploiting the semantic dependencies among table headers and the table title. Our dataset construction framework effectively merged heterogeneous sources from open domain semantic parsing and dialogue-act-based meaning representation tasks by utilizing techniques such as: tree ontology annotation, question-answer pair to declarative sentence conversion, and predicate unification, all with minimum post-editing. We present systematic evaluation on DART as well as new state-of-the-art results on WebNLG 2017 to show that DART (1) poses new challenges to existing data-to-text datasets and (2) facilitates out-of-domain generalization. Our data and code can be found at https://github.com/Yale-LILY/dart.
