Google was founded in 1998 by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University in California. Since then Google has been the lifeline of human life. Honestly, these days it’s hard to imagine a day without Google. It holds answers to almost everything. If you have a question just Google it and you will have the answers within few seconds. This miraculous technology of Google has a huge database in form network web. The web is formed of thousands of sites, blogs, vlogs, etc. So, how does Google know exactly what to show up when something is being searched? The answer is its famous PageRank algorithm.
Named after one of the founders of Google, PageRank is a series of task that acts as a filter to sort out the huge internet database and show only valid and relatable sites when something is being searched by the user. It’s job however doesn’t end here. It also includes arranging the site in a preference that suggests the topmost site might hold accurate results for the user. Sounds like a tedious job, doesn’t it? Working up all the way through the ever increasing internet database, searching the keywords and not to forget- working in thousands of devices simultaneously; Google is no less than a virtual God.
World-renowned network scientist Albert-László Barabási, and Gourab Ghoshal, in a postdoctoral research associate in Barabási’s lab at Northeastern University, recently suggested that the PageRank algorithm can serve as an efficient tool to identify cancer agents in humans. PageRank can use it’s distinguishing and judging ability to survey the protein changes that can shows symptoms of body diseased with cancer. Ghoshal says,
“You can examine how proteins interact with each other and then identify genes based on their PageRank value that are important in determining cancer.”
