Abstract:

Many people are familiar with the issue of plagiarism using information available on the Web. Detecting duplicate documents has also been studied some time because of its importance in Web search engines.

More generally, text reuse occurs whenever somebody "borrows" and modifies facts or statements from a source and uses it in another document.

In this talk, I consider techniques for detecting a wide range of text reuse and how to evaluate them. I will also report on an experiment to determine how much reuse there is in news and blog databases.
