Example Input: Verify if the sentiment of the following document towards the entity Joshua Boyle is Positive .

A U.S. military official said that a military hostage team had flown to Pakistan Wednesday  prepared to fly the family out. The team did a preliminary health assessment of the family and had a transport plane ready to go. But sometime after daybreak there  as the family members were walking to the plane   Boyle  said  he  did not want to board.
Another U.S. official said  Boyle  was nervous about being in "custody" given  his  background.
 Boyle  was once married to Zaynab Khadr  the older sister of former Guantanamo Bay detainee Omar Khadr and the daughter of a late senior al-Qaida financier. Her father  Ahmed Said Khadr  and the family stayed with Osama bin Laden briefly when Omar Khadr was a boy.
Officials had discounted any link between that background and  Boyle 's capture  with one official describing it in 2014 as a "horrible coincidence."
The Toronto Star reported that  Boyle  spoke to  his  parents after  his  release. " Josh  said  he  was doing pretty well for someone who has spent the last five years in an underground prison "  his  father told the paper.
The release came together rapidly Wednesday. It happened nearly five years to the day after Coleman and  Boyle  lost touch with their families while traveling in a mountainous region near the Afghan capital of Kabul.
The couple set off in the summer 2012 for a journey that took them to Russia  the central Asian countries of Kazakhstan  Tajikistan and Kyrgyzstan  and then to Afghanistan. Coleman's parents last heard from their son-in-law on Oct. 8  2012  from an internet cafe in what  Boyle  described as an "unsafe" part of Afghanistan.
 Boyle 's parents say their son told them in a letter that he and his wife tried to protect the children by pretending their signs of captivity were part of a game being played with guards.

Example Input: Verify if the sentiment of the following document towards the entity Charles Taylor is Neutral . Sirleaf  70  acknowledged before the commission in February that she gave up to $10 000 to a rebel group headed by Charles Taylor. Sirleaf said the money she sent while an expatriate was meant for humanitarian services and that she was never a member of the group  the National Patriotic Front.
 Information Minister Laurence Bropleh said Monday evening if the public had had any dissatisfaction with Sirleaf's involvement with Taylor at the time  they would have voted against her in 2005.
 In 2005 the Liberian people knew that President Sirleaf had contributed $10 000 to Taylor's movement  Bropleh said.
 An AP correspondent and others who covered the Liberian war can recall no humanitarian works by Taylor and his fighters  especially in the first months of the war when tens of thousands of refugees were fleeing across the borders to Ivory Coast and Guinea  where they were helped by international and government agencies.
 Then  most atrocities were committed by Doe's forces and Taylor was welcomed as a liberator fighting a barbaric dictatorship.
 "In defense of Ellen Johnson Sirleaf  she never hid the fact that she was curious about Taylor and what he was all about " said Huband  who drove with Johnson Sirleaf on her first trip to meet Taylor in May 1990. "A lot of people supported the idea of Doe being ousted and there had been so many attempts  and they all were foiled  at least one with the help of the American government  which continued to support Doe despite his brutality."
 "I never had the impression that Sirleaf supported Taylor  certainly not after it became clear his troops were out of control " Huband said. "Certainly there was no way she could predict the kind of atrocities that would be committed (by Taylor's fighters) ..."
