 ## Source Data
 
-The original clean FCC invoices are derived from the [RealKIE benchmark](https://indicodatasolutions.github.io/RealKIE/) (FCC Invoices subset). Ground truth annotations were verified and the documents augmented using the [Augraphy](https://github.com/sparkfish/augraphy) library with OCR-safe parameter settings.
+The 75 clean FCC invoices used in this dataset are taken from [**RealKIE-FCC-Verified**](https://huggingface.co/datasets/amazon-agi/RealKIE-FCC-Verified), which re-annotated the FCC Invoices subset of the original [**RealKIE**](https://indicodatasolutions.github.io/RealKIE/) benchmark ([Townsend et al., 2024](https://arxiv.org/abs/2403.20101)) to fix two issues in the original annotations:
+
+1. **Line Item Grouping** — fields previously treated as independent entries are grouped within each individual line item, aligning annotations with real-world invoice structure.
+2. **Annotation Corrections** — erroneous values in the original annotations were corrected.
+
+Starting from these 75 verified documents and their corrected `gt.json` ground truth, this dataset adds noise augmentation using the [Augraphy](https://github.com/sparkfish/augraphy) library with OCR-safe parameter settings, producing up to 18 degraded variants per document for confidence calibration and OCR robustness research.
