[EX Q]: 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.

[EX Q]: Verify if the sentiment of the following document towards the entity Allen Iverson is Neutral . Coach Mike D'Antoni  in particular  was initially enthusiastic about the idea. Walsh had to be convinced. Yet they were so close to making the leap that  as of early Thursday evening  people close to the team were convinced that Iverson was on his way.
 Not surprisingly  there were concerns about Iverson's character. He left his last two teams  Memphis and Detroit  amid controversy. While renowned for his passion on the court  he is infamous for his poor work habits. As the Knicks dug further  they became increasingly concerned about off-court issues  and that concern influenced the final decision. Iverson's agent  Leon Rose  did not return messages on Friday.
 James L. Dolan  the Madison Square Garden chairman  was opposed to Iverson from the start  according to a person who was briefed on the deliberations  but indicated that he would not veto the move if Walsh and D'Antoni wanted to make it.
 The Knicks might have been Iverson's last  best hope to salvage his career and his reputation. Iverson  in turn  might have represented the Knicks' best hope for providing fans with a little excitement.
 "I'm always concerned about that " Walsh said of disappointing the fans. "But I don't think you can build a basketball team based on polls."
