Example Input: Verify if the sentiment of the following document towards the entity Trent Koland is Negative . First responder needed  a hug
Trent Koland  36  who works in Chicago   was having a drink with  his  sister and  her  fiance at the Luxor hotel  which is close to Mandalay Bay  when they noticed groups of people running through the lobby.
Casino staff at first calmly told patrons they would need to move to a different bar. But within seconds  staff instead told  Koland  and other bar patrons they were being relocated to basement tunnels with break rooms and hallways usually used only by staff.
"I thought it was a joke at first " said  Koland   senior art director at Edelman in Chicago  who was in Las Vegas with family celebrating his parents' 40th wedding anniversary. "It was crazy  so they moved us into this break room and we were watching the TV."
Koland and dozens of other tourists taking shelter watched in horror as news accounts on the TV reported a growing number of victims. As more people from outside joined them in the waiting area   Koland  said  he  comforted one woman who was distraught about what  she  had seen.
"There was a woman and she needed a hug  so I just went over there and gave her a hug. She said she was a first responder  and she was ashamed that she didn't do more  " Koland  said by telephone  breaking down into tears at the thought.
 Koland  estimates that  he  and other patrons were moved to the tunnels about 10 p.m.  and were not released to go back outside until 4 a.m. Monday. During that time   he  and others stranded checked social media on their phones and frantically kept up with friends and family to let them know they were safe. Hotel staff brought refreshments and bedsheets so they could lie on the floors of the hallways as they waited   he  said.
"We were just lying in a hallway with other people that didn't know what was going on  " Koland  said  adding that some were worried about friends who were at the concert and had not been accounted for. "We had phone service  I was trying to update my Facebook letting people know I was OK."

Example Input: Verify if the sentiment of the following document towards the entity Nouri Kamal al-Maliki is Neutral . Even with a deadly car bombing and other mayhem marring the day -- the deadline for the American troop pullback under a Jan. 1 agreement -- Prime Minister Nouri Kamal al-Maliki seized on the occasion to position himself as a proud leader of a country independent at last  looking ahead to the next milestone of parliamentary elections in January.
 He made no mention of American troops in a nationally televised speech  even though nearly 130 000 remain in the country; most had already pulled back from Iraq's cities before Tuesday's deadline.
 In a national address  al-Maliki focused his praise on Iraqi troops and security forces for their role in fighting the insurgency. "The national united government succeeded in putting down the sectarian war that was threatening the unity and the sovereignty of Iraq " he said  as if the United States had played no role.
 President Barack Obama  who ran for office on a pledge to end the war  marked the occasion with minimal fanfare  declaring it "an important milestone" even as he warned of "difficult days ahead."
 "The Iraqi people are rightly treating this day as cause for celebration " he said.
 The withdrawal did not command its own presidential appearance -- his brief remarks were delivered at a ceremony honoring entrepreneurs -- a marked contrast with his predecessor  who rarely missed an opportunity to celebrate milestones in Iraq.
 Military experts anticipate more violence in the days ahead. Maliki's effort to capitalize on Iraq's latent anti-Americanism and to extol the abilities of his troops is a risky strategy. If it turns out that Iraqi troops cannot control the violence  al-Maliki will be vulnerable to criticism from rivals -- both if he has to ask the Americans to return but also if he fails to enforce security without them.
 Some American commanders have said they were taken aback by al-Malikial-Maliki's insistence on taking credit for all the security successes in Iraq  but they also see the importance of having him and Iraqi troops appear strong  especially in the face of multiple insurgent factions intent on destabilizing the government.
 Gen. Raymond T. Odierno brushed aside the dismissive tone of Iraqi leaders' public remarks about the Americans  saying that al-Maliki had personally thanked him on Monday night and again on Tuesday for the sacrifices American troops have made.

Example Input: Verify if the sentiment of the following document towards the entity Phelps is Positive . Los Angeles (AFP) –  Swimming great Michael Phelps  revealed that  he  has battled severe anxiety and depression for much of  his  life which drove  him  to consider suicide after  his  success at the 2012 Olympics.
Speaking at a mental health conference in Chicago on Tuesday  the 23-time Olympic gold medal winner talked openly about  his  long battle with crippling depression and is encouraging others to get help like  he  did.
“After every Olympics I think I fell into a major state of depression ”  the 32-year-old Phelps  said.
 Phelps  said  he  reached rock bottom following the 2012 Olympics in London where  he  won four gold medals and two silver. For four days  he  remained in  his  room without food or sleep.
“I didn’t want to be in the sport anymore ”  he  said. “I didn’t want to be alive.”
When  he  hit a low point in  his  depression   Phelps  said  “You do contemplate suicide.”
Over the past two years  Phelps  has opened up about  his  struggles. Once again   Phelps  said  his  depression and anxiety problems have been a staple of  his  life for the past 17 years.
“We’re supposed to be this big  macho  physically strong human beings  but this is not a weakness ”  he  said. “We are seeking and reaching for help.”
 Phelps  won his first gold medal in 2004 at the Athens Olympic Games. That same year the 15-year-old from Baltimore experienced his first “depression spell”.
 Phelps  said as  he  got older  his  depression led to  his  abusing drugs and alcohol.
In 2008  after winning a record eight gold medals at the Beijing Games   Phelps  was photographed smoking from a bong.  He  has also been arrested twice for drink driving.
“It would be just me self-medicating  myself   basically daily  to try to fix whatever it was that I was trying to run from ”  he  said.
 Phelps  isn’t the first Olympic national hero to battle dark demons outside the pool.
Like  Phelps   Thorpe chose to “self-medicate” with alcohol to try and manage  his  vicious mood swings and silence the horrible thoughts going through  his  head.
In an interview with CNN this week   Phelps  said  he  wants to eliminate the stigma associated with mental illness.
“(Mental illness) has a stigma around it and that’s something we still deal with every day ” said  Phelps . “I think people actually finally understand it is real. People are talking about it and I think this is the only way that it can change.”
