Example Input: Verify if the sentiment of the following document towards the entity Boko Haram is Negative . Soldiers will stop and check all motorists passing through Maiduguri and nearby villages throughout the night  while police will take over manning checkpoints during the day  authorities said. The soldiers arrived late Tuesday night  the first sign of a federal government intervention in a city beset by targeted killings by Boko Haram for weeks.
 Zarewa also said police found the unexploded bombs after an alleged Boko Haram bomb attack on a police station in Gamboru  a building destroyed by rioting sect members in July 2009. The rioting  as well as a subsequent security crackdown  left more than 700 people dead.
 Followers of Boko Haram  which means "Western education is sacrilege" in the local Hausa language  went into hiding after the July 2009 riot  as police began arresting anyone caught listening to or holding a sermon by the sect. However  officials now fear the group has rearmed. A video recording released in late June showed a Boko Haram leader calling for new violence as the one-year anniversary of their attack neared.
 Boko Haram has said it wants a stricter version of Islam's Shariah law in place across Nigeria. Nigeria  a nation of 150 million people  is divided between the Christian-dominated south and the Muslim north. A dozen states across Nigeria's north already have Shariah law in place  though the area remains under the control of secular state governments.

Example Input: Verify if the sentiment of the following document towards the entity Christopher Johnson is Positive . Jets Chairman and CEO  Christopher Johnson  navigated through the cacophony and made the smart decision not to institute a playoff mandate next season for Mike Maccagnan and Todd Bowles. Such an ultimatum during this critical juncture of the organizationâs rebuild would only serve to undermine the ultimate goal. It would be reckless and counterproductive. It would threaten to screw everything up.
âItâs always going to be about progress â  Johnson  said this week about how  he âll evaluate the 2018 season. âWe canât get there fast enough. I want to get to the playoffs. I want to get to the Super Bowl. I was serious about that desire to get to the Super Bowl before my brother gets back here. I would love to have that happen. But  there are no mandates. I think the fans are going to be happy with the way we move forward here. I just canât put down a mandate for these guys.â
 Johnson   you see  is smart.  He  knows that setting a postseason-or-else directive is counterproductive. Nothing good  frankly  can come from it.

Example Input: Verify if the sentiment of the following document towards the entity William Ackman is Neutral . ROSELAND  N.J. (Reuters)  - Activist hedge fund manager William Ackman  lost  his  bid to win seats on the board of Automatic Data Processing Inc (ADP.O)  according to a shareholder voting tally read at the payroll processorâs annual shareholder meeting.

Pershing Square did not get any of its three nominees  including  Ackman   elected to ADPâs board  with less than 25 percent of voting shares pledged in support of his proxy campaign.
 Ackman  told Reuters at the meeting that the way the proxy system works put him at a disadvantage  but he felt he accomplished a lot.
 Ackman  launched the ADP proxy contest as an underdog  taking aim at a company engaged in the unglamorous business of providing human resources technology and largely backed by Wall Street. ADPâs share price has more than doubled under Rodriguezâs tenure  and  the company  has posted relatively solid earnings growth.
For three months   Ackman  and ADP have traded increasingly bitter barbs through securities filings  television appearances  conference calls  webcasts and private meetings with investors.
 Ackman  contends that management complacency has turned ADP into an inefficient corporate slugabed pushing outmoded products that even a top sales force could not sell. ADP has countered that  Ackman  brings no new ideas to the table  risks disrupting  the companyâs  steady path to growth and behaves like a âspoiled brat.â
 Ackman âs Pershing Square owns almost 2 percent of ADPâs common shares  making  it  the seventh-largest voting shareholder  according to Thomson Reuters data. When counting unexercised options  the value of the stake is roughly $2.3 billion.
