Google vs. bing

  1. 1. CSCI 590 Spring 2011 BY NIKHIL MESHRAM DUSHYANT SINGH
  2. 2. Google Search Engine Presented by : Dushyant Singh Team GvB
  3. 3. Google's Search Engine <ul><li>Launched by Larry Page and Sergey Brin in 1997. </li></ul><ul><li>Searches for text only. </li></ul><ul><li>Available in 132 languages. </li></ul><ul><li>Google owns over 160 domain names for various countries, besides google.com.[1] </li></ul><ul><li>Monthly Internet Crawl and Indexing. </li></ul><ul><li>Use Page Rank algorithm. </li></ul>
  4. 4. Google's Page Rank <ul><li>Matches the queried string. </li></ul><ul><li>Previous methods used keyword-matching. </li></ul><ul><li>Page Rank analyses human generated links. </li></ul><ul><li>Co-relates to the human aspect of thinking. </li></ul><ul><li>Has been modified to include 200+ indicators and criteria. </li></ul>
  5. 5. Google's Current and Future <ul><li>Snapshots non text content. PDF, Word, Excel, Flash etc. </li></ul><ul><li>Deepweb is still pretty much unaccesible to the search engine. </li></ul><ul><li>Negative reviews of a business would increase the search rank, this problem has been fixed. </li></ul><ul><li>I'm feeling lucky costs Google $110 million/annum. [2] </li></ul><ul><li>Special features: weather, US zipcode, calculations, time, numeric ranges, map, movie showtime, public data, real estate and housing, travel data/airports, package tracking, patent numbers, area code, synonym search and others. </li></ul>
  6. 6. Let's talk stats...

  8. 8. Bing Search Engine Presented by : Nikhil Meshram Team GvB
  9. 9. Let's talk technology...
  10. 10. Search Technology <ul><li>Google's Googlebot is more effective at crawling the web than competing engines </li></ul><ul><li>More sophisticated at filtering out web pages for targeted phrases related to search query </li></ul><ul><li>Good at differentiating between real text patterns and spammy text </li></ul><ul><li>Better than other search engines at determining the true intent of a query and trying to match that versus doing direct text matching. </li></ul>Since 1996
  11. 11. Search Technology <ul><li>Bing's MSNbot (soon to be called “Bingbot”) has gotten better over time at crawling but still not as good as Google at crawling deeply through large sites (such as eBay). </li></ul><ul><li>Does try to process queries for meaning instead of direct text matching – not on par with Google yet. </li></ul><ul><li>Since Microsoft started doing search later in the game, it has a harder time determining natural links from spammy/bought links. </li></ul><ul><li>Still takes longer than Google to get new websites in their index. </li></ul>Since 2005
  12. 12. Bing steals Google search results ... --- and denies it !
  13. 13. <ul><li>It all started with “tarsorrhaphy”. REALLY! </li></ul><ul><li>Tarsorrhaphy is a rare surgical procedure on eyelids. </li></ul><ul><li>Summer of 2010, Google engineers were looking at search results for misspelled query [torsorophy] </li></ul><ul><li>Google returned correct spelling along with the search results. </li></ul><ul><li>At this time Bing had no search results for the same keyword. </li></ul>
  14. 14. <ul><li>Later in the summer , Bing started returning Google’s first result without the offering the spell correction. </li></ul><ul><li>Strange ? </li></ul><ul><li>How could they return our first result to their users without the correct spelling? </li></ul><ul><li>Had they known the correct spelling. </li></ul>
  15. 15. <ul><li>Google asked their engineers to enter some synthetic queries into the search box on the Google home page. </li></ul><ul><li>Within a couple weeks results started appearing in Bing. </li></ul><ul><li>Bing Denies this allegation. </li></ul>
  16. 16. Re-cap <ul><li>Google still on top – used by more Internet </li></ul><ul><li>savvy and business to business searchers. </li></ul><ul><li>Bing skews slightly older, more “shoppers”. </li></ul><ul><li>Bing will be #2 in the search engine </li></ul><ul><li>industry. </li></ul><ul><li>Others in the industry are way behind the curve. </li></ul>Recap
