Example Input: 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.
6.  Larry Ellison

 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.

Example Input: Taylor Swiftâs lawyers  are trying to shake off claims that the âShake It Offâ singer stole lyrics with a new court motion.
 Swift  was sued in September by songwriters Sean Hall and Nathan Butler  who created the song âPlayas Gonâ Playâ for the girl group 3LW in 2001. The duo claimed that  Swift  stole their lyrics and used them in her famous hit single âShake It Off.â
On Wednesday  the singerâs lawyers asked the federal judge to dismiss the copyright lawsuit against  Swift  and argued that the concepts of players playing and haters hating are common music phrases and âpublic domain clichÃ©sâ that canât be claimed as copyright  according to Variety.
 Swift  used the familiar phrase in the chorus of her song which says  âPlayers gonna play  play  play  play  play  and haters gonna hate  hate  hate  hate  hate.â
âThere can be no copyright protection in âplayas  they gonna play and haters  they gonna hate â because it would impermissibly monopolize the idea that players will play and haters will hate â  Swift âs lawyers said. âPlaintiffsâ claim to being the only ones in the world who can refer to players playing and haters hating is frivolousâ¦ Providing a copyright monopoly in the phrase would prevent others from sharing the idea that players play and haters hate.â
To further prove their argument   Swift âs legal team went on to cite other examples of famous songs that use the âplayerâ and âhaterâ phrase such as âDreamsâ by Fleetwood Mac  in which the song says  âPlayers only love you when theyâre playing â and âPlaya Hater â by the Notorious B.I.G.  where the phrase âplaya  playa haterâ is used as the part of the songâs chorus.

Example Input: Image caption Chisako Kakehi  is said to be suffering from dementia
 Chisako Kakehi  is accused of using cyanide to kill  her  lovers and make millions from insurance payouts.  Her  lawyers plan to appeal the sentence.
Prosecutors said  she  targeted wealthy men who were mostly elderly or sick.
 She  became known in Japanese media as the Black Widow  after the female spider which kills its mates after sex.
Kyoto District Court ruled that Chisako Kakehi used cyanide "with a murderous intention" in the four cases  and that  she  should be held responsible for the crimes even though  she  had been diagnosed with dementia.
 Kakehi   who was wearing a hearing aid and asked the judge to speak loudly during the proceedings  showed no emotion when the sentence was handed down.
 Ms Kakehi  was accused of murdering  her  fourth husband  75-year-old Isao Kakehi  on 28 December 2013  a month after they got married.
 She  was also accused of killing two other boyfriends  aged between 70 and 80  and the attempted murder and robbery of another boyfriend - who later died of cancer - between 2007 and 2013.
The trial heard that  she  had joined matchmaking services in which  she  had specifically requested to meet men who were rich and childless.
 She  reportedly inherited around one billion yen ($8.8 million) in all  although  she  later lost some of it through the stock market.
During the 135 day trial  Kakehi  appeared to admit killing  Isao Kakehi   saying  he  had not treated  her  well financially  but later retracted it.
 Her  lawyers said at the time that  her  testimony could not be trusted because of  her  dementia. They have appealed against the death sentence to a higher court  arguing that  her  dementia means  she  cannot be held criminally liable.
