Extreme Google

  1. 1. By Marianne Lenox, HMCPL Staff Training and Development Coordinator Created November 2006 Extreme Google
  2. 2. What is &quot;Google&quot;? <ul><li>Definition: Googol </li></ul><ul><li>Pronunciation: 'gü-&quot;gol </li></ul><ul><li>Function: noun </li></ul><ul><li>Google is a play on the word googol , which was coined by Milton Sirotta, nephew of American mathematician Edward Kasner, and was popularized in the book, &quot;Mathematics and the Imagination&quot; by Kasner and James Newman. It refers to the number represented by the numeral 1 followed by 100 zeros. Google's use of the term reflects the company's mission to organize the immense, seemingly infinite amount of information available on the web. </li></ul><ul><li>Originally called &quot;Backrub&quot;, the logic behind the Google search engine was develop by graduate students Larry Page and Sergey Brin at Stanford University in 1995. Their first place of business was literally a garage. The garage location was chosen because it had a washer/dryer and a hot tub out back, they were already serving 10,000 searches a day. </li></ul>http://www.google.com/corporate/history.html
  3. 3. How We Got Here.... <ul><li>For the last 5 years, Google has been the undisputed leader in online search technology. </li></ul><ul><li>Before Google; Altavista, FAST, and Inktomi had the largest databases; but suffered from poorer search algorithms. </li></ul><ul><li>Google's profit is partially ad driven, but sponsors do not garner higher ratings in searches. </li></ul>

  11. 11.

How many links are actually in the page? </li></ul>Equation: (Exact Phrase Hit)+(AdjacencyFactor)+(Weight) * (PageRank/Links) From: Google 201, Advanced Googology - Patrick Crispen, CSU
  12. 12. Enough!

We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns, the ones we don't know we don't know.&quot; </li></ul>
  14. 14. Wildcards <ul><li>Google supports word wildcards but NOT stemming. </li></ul><ul><ul><li>&quot;It's the end of the * as we know it&quot; works. </li></ul></ul><ul><ul><li>but &quot;American Psycho*&quot; won't get you decent results on American Psychology or American Psychophysics. </li></ul></ul>
