Hi everyone,<\/p>\n
I wanted to share a project I\u2019ve been working on under my solo brand, LegacyDataLabs. As Vision-Language Models (VLMs) grow, I noticed there’s a massive shortage of high-quality, human-validated multimodal datasets for historical handwriting\u2014especially for niche languages like Swedish. Standard OCR engines completely blind-guess these scripts, resulting in pure gibberish.<\/p>\n
To solve this, I built a custom pipeline that bypasses OCR text generation entirely. Instead, it takes pristine digital ePub transcriptions (the absolute “ground truth”) and dynamically synchronizes them page-by-page next to the original high-resolution handwritten manuscript images.<\/p>\n
My first complete dataset is Doktor Glas by Hjalmar S\u00f6derberg (278 multimodal rows), and it is clinically clean. <\/p>\n
\\### \ud83d\udd12 The Tech & Security (Compute-to-Data Sandbox)<\/p>\n
To protect the data from scraping while still making it accessible for model training, I built an air-gapped, isolated Docker environment:<\/p>\n
\\* Zero Data Leakage: External network communication is fully disabled (–network none).<\/p>\n
\\* RAM-Only Access: Training scripts inspect the synchronized JSONL layers directly in intern-memory without file downloading capabilities. <\/p>\n
\\### \ud83d\udce6 Free Sample Available<\/p>\n
I have officially released a 3-page structural sample (sample\\_dataset.jsonl) showing the exact repository keys, author\/title metadata, and chronological image loops.<\/p>\n
You can inspect the sample directly on my Hugging Face profile:<\/p>\n
\ud83d\udc49 https:\/\/huggingface.co\/LegacyDataLabs<\/a><\/p>\n I am currently preparing to scale this pipeline to dozens of historical manuscripts and would love to hear your thoughts! <\/p>\n \\* How are you currently bypassing standard OCR limitations when training VLMs on historical documents?<\/p>\n \\* Would an infrastructure like this be useful for your specific vision-training pipelines?<\/p>\n Looking forward to your technical feedback and suggestions!<\/p>\n Cheers! <\/p>\n<\/div>\n submitted by \/u\/LegacyDataLabs <\/a>
