Row Conditional-TGAN for generating synthetic relational databases [PDF]

open access: yesarXiv, 2022
Besides reproducing tabular data properties of standalone tables, synthetic relational databases also require modeling the relationships between related tables. In this paper, we propose the Row Conditional-Tabular Generative Adversarial Network (RC-TGAN), a novel generative adversarial network (GAN) model that extends the tabular GAN to support ...

Transforming Web Tables to a Relational Database

open access: yes2014 22nd International Conference on Pattern Recognition, 2014
HTML tables represent a significant fraction of web data. The often complex headers of such tables are determined accurately using their indexing property. Isolated headers are factored to extract category hierarchies. Web tables are then transformed into a canonical form and imported into a relational database.
