# A Survey of Graphical Page Object Detection with Deep Neural Networks
## 4 Datasets
### DocBank  
Another dataset to solve document layout analysis is released by [PERSON] et al. [13]. The dataset is known as DocBank, which is the extended version of the TableBank dataset [46]. DocBank is a novel large-scale dataset, and it is constructed by employing weak supervision from the LaTeX documents available on arXiv.com. The proposed dataset comprises 500 thousand document pages with 12 different kinds of semantic blocks such as tables, figures, equations, figures, lists, paragraphs, etc. The authors also define the training/val/test splits in which 400 thousand samples are used for the training purpose, whereas 50 thousand samples are allocated for validation and testing purposes. This large-scale rich dataset extends the opportunities to investigate the blend of deep neural networks employed in computer vision with the methods mainly used in document analysis.

Table 2: Graphical page object datasets. It is important to mention that we have considered equation and formula as semantically equal in this table. Some of these datasets contain as many as 12 page objects [13]. For the sake of convenience, we have only included table, figure, and formula.
