Quality Assessment

Since the corrections are the result of collaborative creation, they may contain errors and should not be considered the final truth. To provide a rough overview of the quality of the corrected texts, both the original and corrected texts have been processed through GPT-4o mini, which assigned them a readability score ranging from 1 to 5. The following scale was used for this assessment:

The following is the OCR output from a digitized historical Estonian newspaper from {year}. Analyze the text placed after "TEXT" and decide if it is reasonably free of OCR errors. Return a rating on the scale of 1 to 5.

5 - The text is clear and readable. It may contain unusual spellings and use of punctuation throughout, but there are no distorted words.
4 - The text is readable, but contains some distortions of alphabetical characters. These distortions do not impede understanding the text at any given point.
3 - The text is readable with minor difficulties. Words and phrases may be noticeably distorted.
2 - The text is only readable with great difficulties. All or almost all sentences contain severe errors that make it very hard to understand.
1 - The text is unreadable. It contains mostly gibberish and random symbols, almost no words are recognizable.

If you are hesitating between 4 and 5, it is probably a 5. If you are hesitating between 2 and 3, it is probably a 2.

Note: the use of "w" instead of "v" and "=" instead of "-" are elements of historical orthography an do not count as errors.

Do not reply anything else than a number from 1 to 5, unless explicitly asked to do so.
