Discussion about post_ocr_correction HOT 8 CLOSED

Yes, in some languages, the results we obtained were below the baseline, but our method is very fast, easy to train and language-independent. Also, notice from Table 1 that we obtained this results with as few as 200 documents.

I don't see how you can build a weighting function using word frequency: remember that the weighting function is what determines the weight of each character in each n-gram when you join them together.

from post_ocr_correction.

The idea of using word frequency to calculate the weight function came from OCR error correction using correction patterns and self‑organizing migrating algorithm. Besides, I hava a question about the challenge of Post-OCR Text Correction. Why doesn't the authorities provide the image data? I think image features are crucial for OCR text correction tasks. Is there any way to get the image data?

Challenge ICDAR2019 Competition on Post-OCR Text Correction

from post_ocr_correction.

The whole purpose of the competition is to correct text when the documents have already been scanned and the image of the document itself has been lost. There is no way to obtain the image data for that particular competition.

Hi Qingkun, do you know how to do all the training all over again? Did you try it?

The author said we can go to notebooks, but the code is outdate and we need to change many things. Have you already change the code in notebooks? Thanks!

Qingkun, I still cannot run it. Could you please try to run it with latest python version and give an example command? Thanks!

This is the command I use, is it correct?
python ./train/train_from_scratch.py -i ./train/data/ICDAR2019_POCR_compttition_dataset -ds SROIE -m ./train/data/models/en/model_en.pt -o ./ --do_train --overwrite_model --overwrite_eval --overwrite_train
