PROBLEM: What is the sentiment of the following document towards the entity Marat Safin ? And with a mangled racket and plenty of kicking and screaming  including a couple of arguments with the chair umpire  then a postmatch parting shot at a line judge Safin called "a little bit too blind."
 Safin used to rant about disliking tennis on grass  and he once complained about the high price and low quality of food at the players' restaurant at the All England Club. Well  he doesn't have to worry about any of that again after bowing out in his final Wimbledon with a 6-2  3-6  7-6 (4)  6-4 loss to Levine.
 After confirming this would be his last appearance at the grass-court Grand Slam tournament -- Safin has vowed to retire at season's end -- he was asked how he feels about being done with Wimbledon.
 He's a former No. 1 player who won the 2000 U.S. Open and 2005 Australian Open  but a series of injuries slowed him recently. Still  Safin came to Wimbledon ranked 24th and seeded 14th  and had to be considered quite a favorite against Levine  who never had defeated anyone ranked better than 67th.
Safin has vowed to retire at season's end -- he was asked how he feels about being done with Wimbledon.
 He's a former No. 1 player who won the 2000 U.S. Open and 2005 Australian Open  but a series of injuries slowed him recently. Still  Safin came to Wimbledon ranked 24th and seeded 14th  and had to be considered quite a favorite against Levine  who never had defeated anyone ranked better than 67th.
 "He's an amazing player  and I'm still kind of feeling weird right now that I just beat Safin  because I've always watched him play on TV " said Levine  who turned pro in 2007. "I just kind of went out there with nothing to lose and played some good tennis."
 Levine was a teen when Safin burst onto the scene as a brash  big-hitting 20-year-old who knocked off Sampras to win the U.S. Open.
 "I really had to ... focus on playing against the ball and not worrying about  'Oh  wow  I'm playing against Marat Safin on the other side of the court '" Levine said. "Because then things could have gotten a lot more interesting."
 As is his wont  Safin made things interesting enough. In the early going  he broke his racket by spiking it on the court.
 Leading 4-3 in the third-set tiebreaker  Safin hit a shot near a line that was ruled out. Afterward  Safin said: "Thanks for the guy who made the call. I want to say hello to him. Too bad that he was a little bit too blind."
 In the fourth set  Safin told the chair umpire he could check for chalk on the ball to confirm a call. Rebuffed  Safin added: "So all players are stupid?"
 Safin reached at least the semifinals at all four majors  including at Wimbledon last year  but he has been criticized for not living up to the potential stored in his 6-foot-4 (1.93-meter) frame -- about 7 inches (18 centimeters) taller than Levine.
 "In the history of tennis  everybody's an underachiever " Safin said. "Agassi should have been winning  I don't know  15 Grand Slams. Sampras should have been winning 20 Grand Slams. Federer should be winning -- already should have 25."
 "I should probably have (won) a couple of more " he said  "but I'm pretty satisfied with what I did."

SOLUTION: Negative

PROBLEM: What is the sentiment of the following document towards the entity John F. Kennedy ? Perhaps no major event in modern U.S. history has spawned more widespread doubt than  the assassination of President John F. Kennedy in Dallas in November 1963 . The official account: One man  Lee Harvey Oswald  did it. The unofficial theory: Well  there are many.
 The JFK assassination  is back in the news as the deadline for releasing a final batch of government documents related to the investigation approaches. Back in 1992  Congress passed a law ordering that all remaining papers be released by Oct. 26  2017 â thatâs this Thursday. President Trump could still decide to keep some information secret on national security grounds  but he seems inclined to allow everything to be released on schedule.
Will this last dossier of evidence put the conspiracy theories to rest? Thatâs unlikely. Despite plenty of evidence to the contrary  most Americans have believed that more than one person was involved in  Kennedy âs death since almost the moment of  the assassination .
According to a new FiveThirtyEight-commissioned SurveyMonkey poll of 5 130 adults  conducted Oct. 17 to Oct. 20  2017  only 33 percent of Americans believe that one man was responsible for  the assassination . A majority  61 percent  think that others were involved in a conspiracy. In pretty much every demographic  most respondents believed that Oswald didnât act alone.
Most people believe JFK wasnât killed by Oswald alone Respondentsâ beliefs about President John F. Kennedyâs death  according to a poll conducted Oct. 17-20  2017 GROUP ONE MAN KILLED JFK OTHERS WERE INVOLVED Overall 33% 61% Male 33 62 Female 32 60 White 38 56 Hispanic 22 72 Black 19 76 College graduate 42 52 No college degree 29 65 White college graduate 48 46 White without a college degree 33 60 Registered voter 35 61 Not registered 25 69 18-34 35 60 35-64 31 62 65 and older 32 60 Republican 36 60 Democrat 36 61 Independent  no lean 24 70 Voted for Hillary Clinton in 2016 38 59 Voted for Donald Trump in 2016 35 61 Source: SurveyMonkey
Thatâs not say that every group believes in a conspiracy theory at equal rates. African-Americans (76 percent) and Hispanics (72 percent) are far more likely than whites (56 percent) to believe that Oswald didnât act alone. The government  of course  has a history of lying to the black community  which may be why African-Americans are more likely to think the government isnât telling the whole story about  Kennedy âs death and other major news stories.
In our SurveyMonkey poll  the 33 percent of people who believe that one man killed  Kennedy  is higher than itâs been in any yearly average of polling since 1966. That was the year before New Orleans District Attorney Jim Garrison publicly accused the government of enacting a huge cover-up to conceal the fact that  the president  had been killed by anti-Communist extremists in the CIA.  He  later prosecuted a man  he  believed was involved in the conspiracy  and though  he  lost  his  conspiracy case in court  Garrison and his theory went on to be immortalized in Oliver Stoneâs 1991 film âJFK.â Although the movie made millions of dollars and fanned the flames of conspiracy  it did not seem to have much impact on American opinion overall â the percentage of Americans who believed in a conspiracy remained pretty stable before and after the filmâs release.
Why is it  though  that belief in a lone gunman has grown by over 20 percentage points in the past two decades? It could be that conspiracy theoristsâ inability to provide proof has hurt their appeal to the public. Itâs also possible that recent computerized evidence seeming to prove Oswald acted alone has gotten through to Americans. Finally  it could be a simple matter of demographic changes. The percentage of Americans who have at least a college degree continues to rise  and SurveyMonkey found that 42 percent of Americans with at least a college degree believed Oswald acted alone compared to 29 percent with less than a college degree. In fact  a slight plurality of whites with at least a college degree actually believed one man was responsible for the death of  Kennedy .
Whatever the cause of the recent upswing in the popularity of the lone assassin theory  most Americans still think that there was a conspiracy and that more than one man was responsible for  Kennedy âs death. Perhaps if the government releases the final documents on the assassination  that will put conspiracy theories about the murder to rest. But chances are it wonât.

PROBLEM: What is the sentiment of the following document towards the entity John Wojnowski ? John Wojnowski  was abused by a priest during a Latin lesson 60 years ago.  He  has spent the past two decades protesting outside the Vatican Embassy in Washington DC. What keeps  him  going?
The most surprising thing about this protester is -  he  doesn't want to protest.
 He  doesn't want to spend eight hours a day on public transport  waiting for buses and trains  getting to and from Embassy Row in Washington DC.
 He  doesn't want to hold  his  sign in the cold  and the dark  and the snow  and the rain.
 He  doesn't want  his  face to freeze   his  knees to ache   his  fingers to turn numb.
 He  was 54 when the protest started;  he  turns 75 in April.  He  has spent almost a third of  his  life here  on  his  own  holding a sign outside the Vatican Embassy.
"Of course I want to stop "  he  says. "But they made it personal."
As day turns to night  and the temperature sinks   John  sits in a bus shelter opposite the embassy  taping three broom handles together.
It's 4:30pm;  he  left home in Baltimore County  around 35 miles north  at 11:30am.
"I waited 45 minutes for the first bus "  he  says. "Then half an hour for the second bus."
From there   he  took a train to Washington's Union Station  a metro to Dupont Circle  before catching a third bus up the hill to the embassy.
When  he  started protesting 20 years ago   John  lived eight miles away in Bladensburg  Maryland  and drove a car.  He  would protest twice a day: a morning shift followed by the rush hour.
Around 10 years ago   his  car gave out  followed by  his  knees. So  he  started using public transport: bus  metro  bus up the hill.
A year ago  he  left Bladensburg to live with  his  son in Baltimore County.  He  no longer protests daily; instead  it's "once  twice  maybe three times a week".
"I try to stay a couple of hours  but it's unpleasant in the dark "  he  says. "In summer I stay longer."
Before  he  moved to Baltimore County   John  came to the embassy every day. After around eight years   he  started taking an annual break to see  his  daughter's family in California.
