Normalized Web Distance and Word Similarity

Rudi Cilibrasi
Paul Vitanyi

The goal of this chapter is to introduce the normalized web distance (NWD) method to determine similarity between words and phrases. It is a general way to tap the amorphous low-grade knowledge available for free on the Internet, typed in by local users aiming at personal gratification of diverse objectives, and yet globally achieving what is effectively the largest semantic electronic database in the world.
