Revising FUNSD dataset for key-value detection in document images

Understand

FUNSD is one of the limited publicly available datasets for information extraction from document im-ages.

• The information in the FUNSD dataset is defined by text areas of four categories ("key", "value", "header", "other", and "background") and connectivity between areas as key-value relations.
• In-specting FUNSD, we found several inconsistency in labeling, which impeded its applicability to thekey-value extraction problem.
• In this report, we described some labeling issues in FUNSD and therevision we made to the dataset.
