Mamma s ranking algorithm

Mamma’s Ranking Algorithm

  • rSort

    • Works like a voting system for search results.

    • The search engines Mamma.com queries often return duplicate results. Instead of simply eliminating the duplicates as many metasearch engines may do, we use this information to rank our results.

    • Each duplicate search result is considered a 'vote' for that result.

    • Pages with the highest number of votes go at the top of our result set (for the mathematicians in the audience, the method of voting we use is a simplified version of the "Condorcet Method", named after the mathematician Marquis de Condorcet who invented this voting procedure in the 18th century).

    • One of the big advantages of this ranking method is the elimination of search engine spam.
