What is Handwritten Data Collection?

Handwritten data collection is the first step to build training datasets to train Optical Character Recognition (OCR) systems to recognize and understand written text.

Handwritten character recognition is a field of research within computer vision that aims to extract information from typed, handwritten or printed text. Optical character recognition engines bridge the gap between humans and machines by allowing all forms of unstructured text data to be edited, searched, indexed and retrieved. Developing handwritten OCR models with high accuracy is still an open problem for researchers and companies alike due to a lack of high-quality training data.

Lionbridge collects handwritten data for machine learning in over 300 languages. With over two decades of experience, Lionbridge develops, calibrates, and improves text-based machine learning applications for the world’s largest corporations.

Handwritten Data Collection Case Studies

DOCUMENT TRANSCRIPTION FOR A NON-PROFIT ORGANIZATION

Lionbridge transcribed hundreds of multilingual handwritten documents dating back hundreds of years, to help a non-profit organization train and build an optical character recognition model.

OCR SYSTEM TRAINING FOR AN AI COMPANY

For an AI company, Lionbridge collected hundreds of samples of handwritten Japanese characters from native speakers. The data was used to train an OCR model to extract data from unstructured documents.
