๐Ÿ“„ Building an AI Invoice Details Extractor โ€” Step 1: Data Collection & Preprocessing
As part of my work on an AI-powered Invoice Details Extractor, Iโ€™ve completed an important intermediate stage of the project: dataset collection and preprocessing.
For this project, I collected the SROIE (Scanned Receipts OCR and Information Extraction) dataset from Hugging Face. The dataset provides receipt images along with OCR information, word-level bounding boxes, and entity annotations, making it suitable for training document-understanding models.
๐Ÿ”น Data Collection
Collected invoice/receipt images and their corresponding annotations.
Extracted OCR words and their spatial coordinates.
Identified key entities such as Vendor, Date, and Total Amount.
Organized the data into a format suitable for model training.
๐Ÿ”น Preprocessing
Processed and normalized the OCR text.
Normalized bounding-box coordinates to a 0โ€“1000 scale.
Converted entity annotations into BIO token-level labels.
Mapped labels to numerical IDs.
Prepared the images, text, bounding boxes, and labels for a LayoutLM-based Transformer model.
Applied tokenization, padding, and truncation to create model-ready inputs.
The goal of this stage was to transform raw receipt data into a structured, consistent, and model-ready dataset, while preserving the relationship between the text and its position within the document.
This preprocessing pipeline forms the foundation for the next stage: training the document-understanding model to automatically identify and extract important invoice information.
๐Ÿš€ Next Step: Model training and evaluation.
