Algorithm
The word 'algorithm' has its roots in Latinizing the name of Muhammad ibn Musa al-Khwarizmi in a first step to "algorismus". Al-Khwārizmī (, , c. 780–850) was a Persian mathematician, astronomer, geographer, and scholar in the House of Wisdom in Baghdad, whose name means 'the native of Khwarezm', a region that was part of Greater Iran and is now in Uzbekistan.
Google Hummingbird
The "Hummingbird" update was the first major update to Google's search algorithm since the 2010 "Caffeine" search architecture upgrade, but even that was limited primarily to improving the indexing of information rather than sorting through information. Amit Singhal, then-search chief at Google, told "Search Engine Land" that "Hummingbird" was the most dramatic change of the algorithm since 2001, when he first joined Google. Unlike previous search algorithms, which would focus on each individual word in the search query, "Hummingbird" considers the context of the different words together, with the goal that pages matching the meaning do better, rather than pages matching just a few words. The name is derived from the speed and accuracy of the hummingbird animal.
