For completeness, lately I've been playing around with the online diff tools at wikEd and at Vroniplag -- and must say that they are both pretty amazing with regard to moved blocks detection. Moved blocks are even detected when they additionally have been edited in one or both copies of the text.

Hi all,

I got that same problem again.

This is the forum to be downloaded this time:
http://www.dasgelbeforum.net/forum.php?page=1041

The link above is actually the oldest/last page. So it would be sufficient to download those 1041 pages including all linked pages (only one level deep).

Any experiences which tool would be the simplest to do this?

Thanks for opinions!

Hi forum,

often I use text comparison tools, for example WinMerge, in order to compare two document versions, for example from different sources.

The problem is that the documents often originate from (different) OCR processes and are only slightly different mainly due to the OCR errors. Therefore, even if the contents of two original documents should be identical, WinMerge often does not recognize this and therefore marks the entire document (erroneously) as completely different.

Therefore my question is whether anyone knows of a text comparison tool that has a even more robust block similarity detection* than for example WinMerge has.

Thanks for hints
