Larry Page and Sergey Brin
The Internet's most famous pair of Ph.D.s are still striving to make data more accessible
 

 
By Cathleen Moore
    
 
  AS THE INTERNET was just beginning to sprout wings in the mid-1990s, two Ph.D. candidates in computer science at Stanford began exploring the relationships between pages on the Internet. What started out as an unassuming research project yielded a system for ranking Web pages that would eventually help guide millions of users each day to information on the Internet.
 
By January 1996, the two students, Larry Page and Sergey Brin, had begun collaboration on a search engine called BackRub, named for its capability of analyzing the back links pointing to a Web page. During this time, Page also explored ways of building a serving environment using low-end PCs instead of large expensive machines, which would become another important component of Google search technology.
 
Google first emerged when Page and Brin bought a terabyte worth of disks and built Google's first datacenter in Page's dorm room. With a proof of concept in hand, the two began pursuing potential buyers in the Web portal arena.
 
In 1998 Page and Brin co-founded Internet search pioneer Google.
 
Google "began with research," says Brin. "Larry and I were working on our Ph.D.s at Stanford when we starting looking at relationships between links on the Web. It turns out our research was complementary and ultimately led to a much more effective way to find information on the Internet."
 
Google is fueled by more than 20 innovations in search technology; the most notable is Page and Brin's PageRank concept of analyzing a Web page's link structure to determine the page's value.
 
PageRank interprets links among pages and analyzes the value of pages that are linked to one another. Links coming from pages that are considered more important or authoritative on a specific subject are given more weight and therefore help increase the PageRank of other pages. This ranking system works in tandem with text-matching technology to boost the relevancy of search results, according to Brin.
 
"Google has demonstrated that high-quality Web searches can be valuable in people's day-to-day lives," Page says.
 
The heady challenge of locating a single page from billions on the Web is complicated by issues such as multiple languages, encodings, and data types, according to Page.
 
"Google answers more than 150 million queries a day. If our technology saves each person even just a few seconds on each search, think how much time and money that saves the world in aggregate," Page says.
 
Google's collection of Web documents, including Usenet discussion posts, images, catalogs, PDF files, and Word documents, recently grew to more than 3 billion, which, according to Page, is the largest of its kind in the world.
 
The company is also setting its sights behind the enterprise firewall, with the recent introduction of the Google Search Appliance. The product puts Google Internet search technology into a software and hardware appliance that can search corporate information.
 
Looking forward, Google's scientists are working to enlarge the technology's scalability to handle the growing size and scope of information on the Internet.
 
"Google is expanding the reach of its services to include more and more information," Page says. "[Our] mission is to organize the world's information and make it accessible and useful."
