论文摘要
结构化信息是自动验证事实主张的重要知识来源。然而，对该任务的大多数研究都集中在文本数据上，并且最近对结构化数据的少数查询是针对封闭域设置的，在假定已经检索到每个索赔的适当证据的地方。在本文中，我们调查了对开放域设置中结构化数据的验证，引入了关节重新依赖和验证模型，该模型将融合了验证部分中的证据文档。我们的开放域模型的性能与TabFact数据集上的封闭域的最新域相媲美，并通过包含多个表格以及对启发式检索基线的重大改进来证明性能提高。
Structured information is an important knowledge source for automatic verification of factual claims. Nevertheless, the majority of existing research into this task has focused on textual data, and the few recent inquiries into structured data have been for the closed-domain setting where appropriate evidence for each claim is assumed to have already been retrieved. In this paper, we investigate verification over structured data in the open-domain setting, introducing a joint reranking-and-verification model which fuses evidence documents in the verification component. Our open-domain model achieves performance comparable to the closed-domain state-of-the-art on the TabFact dataset, and demonstrates performance gains from the inclusion of multiple tables as well as a significant improvement over a heuristic retrieval baseline.
