Example Input: Verify if the sentiment of the following document towards the entity John F. Kennedy is Neutral . BOSTON (Reuters) - More than half a century after  U.S. President John F. Kennedy  was struck down by an assassinâs bullet in Dallas  Texas  the United States is due on Thursday to release the final files on the investigation into the killing that rattled a nation.

Academics who have studied  Kennedy âs slaying on Nov. 22  1963  said they expected the final batch of files to offer no major new details on why Lee Harvey Oswald gunned down the first and only Irish-American Roman Catholic to hold the office.
They also feared that the final batch of more than 5 million total pages on the  Kennedy  assassination held in the National Archives will do little to quell long-held conspiracy theories that the 46-year-old presidentâs killing was organized by the Mafia  by Cuba  or a cabal of rogue agents.
Thousands of books  articles  TV shows and films have explored the idea that  Kennedy âs assassination was the result of an elaborate conspiracy. None have produced conclusive proof that Oswald  who was shot dead a day after killing Kennedy  worked with anyone else  though they retain a powerful cultural currency.
âMy students are really skeptical that Oswald was the lone assassin â said Patrick Maney  a professor of history at Boston College. âItâs hard to get our minds around this  that someone like a loner  a loser  could on his own have murdered  Kennedy  and changed the course of world history. But thatâs where the evidence is.â

In 1992  Congress ordered that all records relating to the investigation into  Kennedy âs death should be open to the public  and set a final deadline of Oct. 26  2017 for the entire set to be made public.
 Kennedy âs assassination was the first in a string of politically motivated killings  including those of  his  brother Robert F. Kennedy and civil rights leader Martin Luther King Jr.  that stunned the United States during the turbulent 1960s.  He  remains one of the most admired U.S. presidents.

Example Input: Verify if the sentiment of the following document towards the entity Jacob Zuma is Neutral . South Africa's parliament spokesman says the speaker has received  Jacob Zuma's  resignation letter and  his  departure as president is effective immediately.
 Zuma  announced  his  resignation late Wednesday after the ruling African National Congress ordered  him  to step down. The ANC has been hurt by multiple corruption allegations around  Zuma   who has denied wrongdoing.
South Africa's government says acting President Cyril Ramaphosa is in charge until parliament elects a new leader Thursday afternoon following the resignation of  Jacob Zuma .
 Zuma  resigned late Wednesday after the ANC  which has lost popularity because of corruption scandals during  his  tenure  instructed  him  to leave. Ramaphosa has promised to fight graft.
The South African currency strengthened against the dollar in early trading Thursday after  Zuma 's resignation  which ended a leadership crisis that had stalled some government business.
The Nelson Mandela Foundation welcomes  Zuma 's departure but says the state must act against "networks of criminality" that have hurt South Africa's democracy.

Example Input: Verify if the sentiment of the following document towards the entity Mohammed Bin Salman is Positive . The heir to Saudi Arabiaâs throne has accused  Iran  of âdirect military aggressionâ which could be an âact of war â after Saudi air defense forces intercepted a ballistic missile on Saturday fired toward the capital  Riyadh  from across the border in Yemen.
Yemen has been embroiled in a civil war since 2015 between a Saudi-led military coalition in support of the Yemeni government  and Houthi rebels believed to be funded by  Iran .
âThe involvement of  Iran  in supplying missiles to the Houthis is a direct military aggression by the Iranian regime â the Saudi news agency SPA reported  Crown Prince Mohammed Bin Salman  as saying on Monday  âand may be considered an act of war against the Kingdom.â The language closely matched a statement earlier given by the Saudi-led coalition.
 Iran  immediately denied  it  was behind the missile launch.
The head of the Saudi military coalition said that experts in military technology had examined other missiles and âconfirmed the role of  Iran âs regime in manufacturing these missiles and smuggling them to the Houthi militias in Yemen for the purpose of attacking the Kingdom  its people  and vital interests.â
 The crown princeâs  reported remarks mark a new height in tensions between  Iran  and Saudi Arabia  the regionâs rival powers. The civil war in Yemen is widely seen to be a proxy war between the two countries  and has resulted in the deaths of over 10 000 civilians and triggered a humanitarian disaster including a cholera outbreak which has infected nearly a million people.
