OPEN: Find a fast/efficient method to spell correct / improve OCR errors

Fix text with OCR errors:

"""
Η εναλλαγή των εποχών παφαμένει για τον άνθρωπο ένα μυστήριο. Κάθε χρόνο η ίδια επανάληψη και κάθε φορά το ίδιο πρωτόγνωρη, μαγική και ανεξήγητη»: ένα θαύμα, μια μαφτυρία της ξωής, μια φωγμή έκπληξης. Πριν η φύση γίνει μονότονη, αλλάζει και μας παφασύρει κι εμάς στους Qυθμούς της ανανέωσης και της ποικιλίας. Ό,τι κάνει την άνοιξη πρωτίστως πρόκληση ζωής είναι ότι δεν αποτελεί μόνον υπόθεση της φύσης αλλά και διχή μας.

I’d like to work on this issue if it’s still open.
My approach would be a lightweight OCR-correction pipeline using character normalization + edit-distance spell correction, followed by context-based scoring (n-grams / LM) for Greek text.

Please let me know if I can be assigned. Thanks!

Hello
I’d like to work on this issue.

I’ve already handled similar OCR-related text normalization problems in a previous project, where I worked on post-OCR cleanup for noisy text (character substitutions, Latin–Greek confusion, and word distortions) to improve downstream NLP quality. That experience is directly relevant here.

My proposed approach for this issue:

First, I’ll add a focused test in test_corpus_clean_enhancements.py using real Greek OCR output to reproduce the problem and ensure it’s not falsely classified as mojibake or non-Greek noise.

I’ll analyze the current cleaning heuristics and noise scoring to identify why valid Greek OCR text with character substitutions is being misclassified.

Then, I’ll introduce minimal, language-aware adjustments (or normalization rules) so common Greek OCR errors (e.g., φ→ρ, Latin Q→Greek ρ, distorted word forms) are handled correctly without affecting existing safeguards.

Finally, I’ll verify the fix by running the relevant test suite and ensuring no regressions in the pipeline behavior.

I’ve already started validating this locally and am confident I can deliver a clean, well-tested fix that aligns with the current design philosophy of GlossAPI.

If this approach sounds good, I’d be happy to take ownership of the issue.

Thank you!

Hi, you will need the help of a native greek speaker for this one please go to our discord and see if you find anyone interested
