PROBLEM: Verify if the sentiment of the following document towards the entity Jacob Zuma is Neutral . The cartoon caused a storm when the Times published it in 2008  two years after Jacob Zuma had been acquitted of rape charges. But van der Berg said Zuma had not followed up on threats to sue until now.
 Zuma is claiming 4 million rand (about $570 000) for humiliation and degradation and 1 million rand (about $140 000) for damage to his reputation. His spokesman  Zizi Kodwa  refused to comment Tuesday.
 The cartoon also showed Zuma's political allies encouraging him as they held down a writhing  screaming figure with a sash identifying her as the "justice system."
 It appeared in the newspaper as Zuma's political party led a protest campaign to have the corruption charges dropped against him. Zuma at the time was preparing to lead his African National Congress party in general elections. Prosecutors dropped the charges on the eve of the vote  and Zuma took office in 2009.
 Buti Manamela  then a leader of the Young Communist League  filed a formal complaint about the cartoon before South Africa's Human Rights Commission in 2008. The South African Communist Party leader was among the ANC allies depicted in the cartoon.

SOLUTION: no

PROBLEM: Verify if the sentiment of the following document towards the entity Jenny Chang is Neutral . A few years ago he began working with Dr. Jenny Chang  medical director of the Lester and Sue Smith Breast Center at Baylor College of Medicine.
 Chang had performed a number of biopsies on breast cancer patients  both on those whose cancers were confined to the breast and on those whose cancers had metastasized to the brain.
 From those biopsies  Chang said she had identified a number of genetic pathways ways in which gene mutations affected the ability of the cancer to spread unique to patients who developed metastatic breast cancer.
 "But I had a lot of trouble with the data and trying to translate it into clinical practice " she said. She couldn't find her way out from beneath the avalanche of data.
 So she turned to Wong.
 Using his mathematical modeling  Wong sifted through Chang's data and the large databases of genome and clinical trial data. Out of that  he identified several candidate drugs to impair the genetic pathways that helped the cancer spread.
Chang's data and the large databases of genome and clinical trial data. Out of that  he identified several candidate drugs to impair the genetic pathways that helped the cancer spread.
 One of them  a drug named sunitinib  which treats a kidney cancer called renal cell carcinoma  emerged as the best bet. Chang then tested the drug in mice  and the study showed it prevented breast cancer from spreading to the brain.
 She has already begun a Phase II clinical trial of the drug  enrolling nine patients with metastatic breast cancer  and she is looking for more.
 "The drug is very well-tolerated by patients  and so far the trial is going very well " Chang said.
 But by using an existing drug  Chang and Wong could skip the lengthy Phase I  during which a drug is checked for safety. If Chang's tests go well  sunitinib could be on the market within a few years for metastatic breast cancer.

SOLUTION: no

PROBLEM: Verify if the sentiment of the following document towards the entity Rogelio Martinez is Neutral . Rogelio Martinez  died while patrolling in the Big Bend Sector of the border in Texas. The agent and  his  partner were responding to activity near a freeway in the Van Horn Station area when they were attacked.  Martinez ’s partner  Stephen Garland  survived.
The manner of  Martinez ’s death is still “undetermined.”
 Martinez ’s fiancée  Angie Ochoa  said she believes the autopsy report is cover-up.
Ochoa said the FBI is focusing on the medication in  Martinez ’s body instead of finding the person who killed  him .

SOLUTION:
yes
