Over time, the algorithm is updated or enhanced to improve the quality of Google search results. What is surprising is that the sophistication of the algorithm is made by an Indian-led team. He is Amit Singhal.
Amit Singhal (full name of Amitabh Kumar Singhal) was born in 1968 in Jhansi, a city in Uttar Pradesh, India. Little Amit likes Star Trek movies. From that penchant, he has the dream of making robots that can speak to humans.
Amit Singhal earned a bachelor's degree in computer science from the Indian Institute of Technology Roorkee in 1989. Amit then went on to study at the University of Minnesota Duluth, USA and earned a M.Sc in computer science in 1991. He then went to college S-3 at Cornell University, New York, USA.
After earning his Ph.D. In 1996, Amit Singhal worked as a researcher at AT & T Labs. The field of research is information retrieval and speech retrieval. In 2000, Amit joins Google for his small friend's persuasion, Krishna Bharat (creator of Google News, a service that automatically indexes over 25,000 news sites in over 25 languages).
At Google, Amit Singhal is Head of the Search Quality Team. He said to Sergey Brin: "Your search engine is very good, but let me rewrite the algorithm."
In 2001 Amith Singhal rewrote Google's algorithm so the algorithm has a new ranking system and is able to distinguish Apple (software) and apple (fruit). For his achievement, Amith was awarded the Google Fellow, an honors degree awarded to a handful of the most successful Google engineers.
Not necessarily stop there, Amit and his team add new features in the Google algorithm to ensure that Google search results are relevant and qualified. Two very famous features are Panda and Penguin. Panda Algorithm is a filter to lower the ranking of sites / blogs whose content quality is low (eg blogs containing content automatically / AGC, spin results, bad grammar, etc.). The Penguin algorithm is a filter to downgrade sites / blogs that violate Google's Quality Guidelines such as paid backlinks and spam comments.
Amith Singhal rewrote Google's algorithm in 2013. This new algorithm called Hummingbird is capable of displaying complex query searches. Currently, Amit is streamlining Google's algorithm so as to provide search results from voice-based queries.
For Amith, it seems Google is the right place to realize the dream of his childhood to make a robot. Not a robot made of iron and steel, but a virtual robot created from the algorithm.
