New comparative analysis technique can organize any electronic information

This is Science Today. Using a computer technique commonly used to detect plagiarism in books, college papers or computer programs, a team of researchers at the University of California, Berkeley came up with an improved method for comparing whole genome sequences. But chemist Sung-Hou Kim says their technique, called feature frequency profile, is so general that any electronic information can be organized.

Kim:    So, for example, let's say you would like to organize all the books or libraries without preconceived notion of what's the name of the title, who's the author, based on content alone because this method doesn't really depend on knowing the author or genre. You just content yourself and you can group them. So, if you are interested in this book, I can suggest to you - you know, these are the books that are similar for example and we can also index them because mathematics allows you to index them. So, I think this kind of approach can be extended in application in many different places.
