I want to compare two editions of one book. The book is very long and the editions are close but not identical.
I have extracted the texts with OCR. The obtained text-files have mistakes and many things left from text formating. Now I want to make a rough comparison of the text-files --- I want to ignore most of the things, but I need to capture something like a sentence or at least new paragraph.
The file comparison (like meld) does not seem to be useful for this (ignoring white space does not help at all).
