Do you have documents in an endangered language that require digitization? We can build OCR models for your data! Let us know here.

Come to our live QA session at EMNLP 2020 at Gather Session 4: Machine Translation and Multilinguality! Details here.

Instead, we focus on post-correcting the OCR output from a general-purpose OCR system.

In this paper, we present:
