Due to the characteristics of Information and Communications Technology (ICT)
products, the critical information of ICT devices is often summarized in big
tabular data shared across supply chains. Therefore, it is critical to
automatically interpret tabular structures with the surging amount of
electronic assets. To transform the tabular data in electronic documents into a
machine-interpretable format and provide layout and semantic information for
information extraction and interpretation, we define a Table Structure
Recognition (TSR) task and a Table Cell Type Classification (CTC) task. We use
a graph to represent complex table structures for the TSR task. Meanwhile,
table cells are categorized into three groups based on their functional roles
for the CTC task, namely Header, Attribute, and Data. Subsequently, we propose
a multi-task model to solve the defined two tasks simultaneously by using the
text modal and image modal features. Our experimental results show that our
proposed method can outperform state-of-the-art methods on ICDAR2013 and UNLV
datasets.

提出了一种基于图的表格结构识别（TSR）任务和表格单元格类型分类（CTC）任务的多任务模型，通过使用文本模态和图像模态特征来同时解决这两个任务，旨在将电子文档中的表格数据转化为可机读格式，并为信息提取和解释提供布局和语义信息。实验结果表明，该方法在 ICDAR2013 和 UNLV 数据集上的性能优于现有的方法。
