Task Decomposition for Efficient Annotation

arXiv:2606.24734v1 Announce Type: cross Abstract: High-quality annotations of structured representations are expensive to collect over large corpora. Manual annotation of structure is laborious, and model-based annotation, although cheaper to generate, requires expensive validation and potentially significant supervision to ensure that the annotation quality is strong enough to be useful downstream. In traditional annotation workflows, annotation of each complete example is performed end-to-end by a single annotator. However, structured annotation is complex, and each aspect of the task repres

Why this matters
Why now

The increasing complexity and scale of AI models necessitate more efficient and high-quality data annotation processes to maintain progress and reduce costs.

Why it’s important

Improving annotation efficiency directly impacts the development speed, cost, and accuracy of AI systems, affecting industries reliant on machine learning models.

What changes

Traditional end-to-end annotation workflows will be re-evaluated and potentially replaced by more modular, decomposed task approaches, leading to higher quality and lower-cost data.
