AI Handwritten document recognition service - Help to train the service

Hello,

I'm working with your recognize text cognitive service and this service is very powerfull. I have some old handwritten document to parse and the service not recognize propertly the text.
If I well understand your system is based on dataset to recognize handwritten document, I have some errors during the parsing.
I want to know if I can contribute to your project, I can provide several handwritten documents and the parsing if necessary.
Do you have any possibility to contribute to this project ?

Regards,
Kevin RAMAGE
