Syntactic Clustering of the Web

Andrei Z. Broder, Steven C. Glassman, Mark S. Manasse, Geoffrey Zweig

We have developed an efficient way to determine the syntactic similarity of files and have applied it to every document on the World Wide Web. Using this mechanism, we built a clustering of all the documents that are syntactically similar. Possible applications include a "Lost and Found" service, filtering the results of Web searches, updating widely distributed web-pages, and identifying violations of intellectual property rights.
