Q: Verify if the sentiment of the following document towards the entity Chris Caldwell is Neutral . These primes are exceedingly rare and sporadic  said Chris Caldwell  a professor of mathematics and statistics at the University of Tennessee at Martin  who studies prime numbers and has written a history of the Mersenne primes.
"Finding a prime is not going to change any theorems in mathematics  but this is a type of prime that has been interesting to mathematicians since several centuries before Christ "  Caldwell  said. Even the ancient Greek mathematician Euclid talked about what would later become the Mersenne primes  he said.
 Caldwell  added that the discovery was akin to breaking a land speed record.
The last few Mersenne primes have been closer to each other than the researchers expected   he  said.
The numbers seem to occur sporadically because researchers don't fully understand the pattern they follow   he  said. "So you expect in any process that appears random to have some close groupings of numbers. But  we  didn't expect to find another one so soon after the last one."
"In the long run   we  hope to use these data to predict how often these occur "  he  added.

Q: Verify if the sentiment of the following document towards the entity Larry Ellison is Positive . These American billionaires also share a few quirks: Microsoft founder Bill Gates  Facebook CEO Mark Zuckerberg   Oracle founder Larry Ellison  dropped out of college. Jeff Bezos  Larry Page and Sergey Brin all went to Montessori schools  where children are encouraged to think independently and creatively rather than following traditional rules. It seems  too  that billionaires really like houses in Hawaii.
As is the case with the richest women in America  the richest people in America donate a lot of money to causes they care about. Some of the men on this list have donated hundreds of millions into research designed to improve human lifespan and eradicate dangerous diseases  such as Alzheimerâs disease and cancer. Warren Buffett  Gates  Zuckerberg  and  Ellison  have gone a step further and promised to give their fortunes away as part of The Giving Pledge  an initiative designed by Buffett and Gates to encourage billionaires to funnel their vast wealth to philanthropy.

 Ellison   73 â another college dropout â co-founded the software firm Oracle in 1977. In addition to owning about 25% of the company  he also owns the entire Hawaiian island of Lanai  a sailing team and even an entire tennis tournament  the New York Times reports.
While known for living large (the billionaire owns a 288-foot yatch)   Ellison  started out with modest ambitions.  His  parents  who adopted  him  when  he  was nine months old  wanted  him  to be a doctor  but  he  left school when  he  realized medicine didnât interest  him .  He  moved to California and worked as a computer programmer and a rock-climbing instructor and river guide  according to the Times. At this point   Ellison  said  he  was âpretty happy with  his  life.â
But after a series of jobs   he  became part of a company working to establish a new type of software database. That company would become Oracle  now one of the largest software companies in the world.
 Ellison   like other titans on this list  is interested in extending human lifespan  and has given over $330 million for research into aging and related diseases.
Four-times divorced   Ellison  has two adult children and calls  his  $70 million Woodside  Calif. estate home. However   Ellison âs massive real estate portfolio means  he  never spends much time in one place.  He  owns additional properties in Japan  San Francisco  Malibu  Lake Tahoe and Rhode Island.
