This data repository contains the key datasets required to reproduce the paper "Scrambled text: training Language Models to correct OCR errors using synthetic data".In addition it contains the 10,000 synthetic 19th century articles generated using GPT4o. These articles are available both as a csv with the prompt parameters as columns as well as the articles as individual text files.
The files in the repository are as follows
- ncse_hf_dataset: A huggingface dictionary dataset containing 91 articles from the Nineteenth Century Serials Edition (NCSE) with original OCR and the transcribed groundtruth. This dataset is used as the testset in the paper
- synth_gt.zip: A zip file containing 5 parquet files of training data from the 10,000 synthetic articles. The each parquet file is made up of observations of a fixed length of tokens, for a total of 2 Million tokens. The observation lengths are 200, 100, 50, 25, 10.
- synthetic_articles.zip: A zip file containing the csv of all the synthetic articles and the prompts used to generate them.
- synthetic_articles_text.zip: A zip file containing the text files of all the synthetic articles. The file names are the prompt parameters and the id reference from the synthetic article csv.
