Leveraging Text Repetitions and Denoising Autoencoders in OCR Post-correction

no code implementations26 Jun 2019 Kai Hakala, Aleksi Vesanto, Niko Miekka, Tapio Salakoski, Filip Ginter

A common approach for improving OCR quality is a post-processing step based on models correcting misdetected characters and tokens.

Denoising Optical Character Recognition

Evaluation of a Prototype System that Automatically Assigns Subject Headings to Nursing Narratives Using Recurrent Neural Network

no code implementations WS 2018 Hans Moen, Kai Hakala, Laura-Maria Peltonen, Henry Suhonen, Petri Loukasm{\"a}ki, Tapio Salakoski, Filip Ginter, Sanna Salanter{\"a}

Our aim is to allow nurses to write in a narrative manner without having to plan and structure the text with respect to sections and subject headings, instead the system should assist with the assignment of subject headings and restructuring afterwards.
