  Despite its increasing role in communication, the world wide web remains the
least controlled medium: any individual or institution can create websites with
unrestricted number of documents and links. While great efforts are made to map
and characterize the Internet's infrastructure, little is known about the
topology of the web. Here we take a first step to fill this gap: we use local
connectivity measurements to construct a topological model of the world wide
web, allowing us to explore and characterize its large scale properties.
