摘要:

在科学论文中,数值表被广泛用于表示实验结果。对于表的理解,度量类型对于区分表中的数字至关重要。我们介绍了一个新的信息抽取任务,从多层次的标题数字表的度量类型识别,并提供了一个数据集提取的科学论文组成的标题表,标题,和度量类型。然后,我们提出了两个联合学习的神经分类和生成方案,具有基于指针生成器和基于BERT的模型。我们的研究结果表明,联合模型可以处理在报头和报头外的度量类型识别问题。

英文摘要:

Numerical tables are widely used to present experimental results in scientific papers. For table understanding, a metric-type is essential to discriminate numbers in the tables. We introduce a new information extraction task, metric-type identification from multi-level header numerical tables, and provide a dataset extracted from scientific papers consisting of header tables, captions, and metric-types. We then propose two joint-learning neural classification and generation schemes featuring pointer-generator-based and BERT-based models. Our results show that the joint models can handle both in-header and out-of-header metric-type identification problems.
