Study Reveals Web Sites are Only 19 Mouse Clicks Apart
The study was led by physics professor Albert-Laszlo Barbasi at the University of Notre Dame, who, along with his team, had a robot collect and follow all links found on one Web page. The process was repeated until the team could determine a statistical link between two pages.
The reason for the study was primarily to benefit search engines, who can now create programs using the statistics to determine the information available via the Web. It is estimated that any of the search engines only retrieve about 34 percent of the information available over the Internet.
