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. Initial experiments done at RMIT and UMass indicated that there was little difference between similarity measures in their ability to detect reuse. In this talk, I will describe more recent experiments with similarity measures and a fingerprint technique to detect how much reuse there is in news and blog databases.
