Question ID: 376603

I would like to find an appropriate way to compare two documents and
if possible from two different sources, such as MS Word and a Web site
or a Text file or a PowerPoint presentation and so on.

A commercial or shareware application would be acceptable.

I have two goals:

1. Find out if I'm presented with non-genuine content.
2. Pinpoint changes which were made to documents, in the process of
them being reviewed, without the right tracking triggers being
switched on to monitor them and that ending up being a hassle to
identify where changes have been made.

Thank you.

Dear Mao,

Anti-plagiarism software is software designed to identify similar
texts--thus identifying plagiarized texts. Web based services compare
material saved in your computer with material from the Internet.


?This program examines a collection of document files. It extracts the
text portions of those documents and looks through them for matching
words in phrases of a specified minimum length. When it finds two
files that share enough words in those phrases, WCopyfind generates
html report files. These reports contain the document text with the
matching phrases underlined.?
