AI-Powered Digitization of Complex Historical Ledgers

(Client: SBL Knowledge Systems)

Key Challenges

Intricate Handwritten Script:
Deciphering and structuring data from thousands of unique historical ledgers. These documents featured dense, flowing traditional script with significant character variations, ligatures, and closely spaced lines, demanding highly specialized OCR capabilities

High Volume & Accuracy:
Processing over 13,000 such images to produce more than a million structured data rows, while ensuring an accuracy rate exceeding 90%

Advanced AI-Powered Interpretation

Utilized cutting-edge Optical Character Recognition (OCR) technology, specifically adapted to handle the complexities of the dense, traditional handwritten script. Sophisticated Large Language Models (LLMs) were then employed for intelligent interpretation of OCR output, structuring the data, and even generating scripts for data cleansing and final Excel formatting according to precise client specifications

Innovative Workflow Automation

Developed and meticulously refined sophisticated prompts to guide the AI language models. This enabled accurate data extraction and transformation directly into client-specified Excel layouts and allowed for the creation of an entire workflow, including easy-to-follow GUIs, using advanced AI without direct manual coding
