In this paper we propose an approach for simultaneously normalizing and lemmatizing Old Literary Finnish into modern spelling. ...
There have been several projects in Finland that have digitized old publications and made them available for research use. However, using modern NLP methods in such data poses great challenges. ...
Bollmann & Søgaard (2016) have shown that a bi-directional long short-term memory (bi-LSTM) can be used to normalize historical German texts. ...

The ancient historical documents are generally preserved as digitised texts using Optical Character Recognition (OCR) technique. ...
But the development of OCR for Tamizhi documents is highly challenging as many characters have similar shapes and structures with very small variations. ...
Tamizhi document images are given as training data for the network. The reason for using this architecture is, OCR is an image-based sequence recognition problem. ...
