 Description

ENGLISH During the project L11 - Error models for OCR of The Language Technology Programme 2019-2023, various OCR post-processing models were trained. This is the best performing one. On texts from the 19th century to the early 20th century, it reduces word error rate from 6.49% to 3.08%, and character error rate from 1.39% to 0.73%. On modern texts, it reduces word error rate from 5.52% to 3.60% and character error rate from 1.17% to 1.0%. More info, such as how to use the model for inference, in README. ICELANDIC Í verkefninu L11 - Error models for OCR í Máltækniáætlun 2019-2023 voru nokkur ljóslestrarvilluleiðréttingarlíkön þjálfuð. Þetta er best þeirra. Líkanið lækkar hlutfall orðavillna (e. word error rate) úr 6,49% í 3,08% í textum frá 19. öld og fyrri hluta 20. aldar og hlutfall stafvillna úr 1,39% í 0,73%. Í nútímamálstextum lækkar það hlutfall orðavillna úr 5,52% í 3,60% og hlutfall stafvillna úr 1,17% í 1,0%. Nánari upplýsingar, svo sem hvernig má nota líkanið, er að finna í meðfylgjandi README-skjali.
