Bounding Box Label Propagation for Re-Annotation of Document Layout Analysis Datasets

arXiv:2606.17644v1 Announce Type: cross Abstract: Datasets in practical document processing scenarios typically grow over time, and their class annotations undergo continuous refinement. This creates significant re-annotation efforts, which are time-consuming and costly. A promising remedy is to re-annotate only a small subset of available documents manually and apply semi-supervised learning techniques that leverage both labelled and unlabelled data. Although there are numerous approaches to tackle this problem for classification, there exists no adaptation for the problem of re-classifying o

Why this matters
Why now

The continuous growth and refinement of datasets in practical document processing demand more efficient re-annotation methods, making semi-supervised learning increasingly relevant.

Why it’s important

Improving the efficiency of re-annotation reduces costs and time, accelerating the development and deployment of document AI systems across various industries.

What changes

The adoption of methods like bounding box label propagation will make document layout analysis more scalable and adaptable to evolving data, rather than requiring full manual re-annotation.
