NEW YORK: Four Indians are among Fortune magazine's list of 20 "extraordinary" technology czars and young entrepreneurs analysing data and processing big numbers to discover information that will "transform the way businesses operate."

Fortune's maiden 'Big Data All-Stars' lists the 20 extraordinary people who are "the best at connecting the dots and digging deep."

Among the 20 is Arun Murthy, who co-founded business computer software company Hortonworks.

Murthy started off at Yahoo when Hadoop, the open-source storage and processing software that powers much of the web's big data, was an early prototype.

His team's mission was to scale it for Yahoo's web search and Murthy helped develop a resource and workload management system called YARN that acts as a sort of operating system for Hadoop, Fortune said.

Next on the list is Surabhi Gupta, a software engineer at popular travel rentals website Airbnb.

As a graduate student in computer science at Stanford University, Ms Gupta became fascinated by the art of summarisation, which is extracting meaning from text without actually reading the text.

Gupta was working at Google when she started researching a trip using Airbnb.

The possibilities Airbnb's data offered fascinated her and in the four months at the room rental service company, overhauled and improved their search engines and is currently working on condensing all of Airbnb's listings to create summaries to enable users to understand different cities' vibes, the publication said.
