Given a document and an entity the task is to select the author's sentiment towards the entity. Sentiments can be Positive, Neutral and Negative. Select Positive if the article expresses a positive view towards the given entity or praises its quality or skills. Select Neutral if the document expresses no clear view towards the entity or has equal amounts of positive and negative statements or expressing some fact/quote by someone else. Select Negative if the article expresses a negative view towards like harsh remarks, criticizing entities action/decision etc. Note that URLs in the text have been replaced with [Link].

Example Input: What is the sentiment of the following document towards the entity Joachim Frank ? The 2017 Nobel Prize in chemistry has been awarded to  researchers Jacques Dubochet  Joachim Frank and Richard Henderson  for  their  work that developed cryo-electron microscopy  which the Royal Swedish Academy of Sciences says "both simplifies and improves the imaging of biomolecules."
Speaking to the prize committee by phone Wednesday morning   Frank  said  he  had thought the chance of  him  winning the prestigious honor was "minuscule."
 He  added that cryo-electron microscopy "is about to completely transform structural biology " saying the technology is being taken up by a new generation of medical researchers.
Dubochet is affiliated with the University of Lausanne  in Switzerland;  Frank  is affiliated with Columbia University in New York; Henderson is affiliated with the MRC Laboratory of Molecular Biology in Cambridge  U.K.
"Electron microscopes were long believed to only be suitable for imaging dead matter  because the powerful electron beam destroys biological material. But in 1990  Richard Henderson succeeded in using an electron microscope to generate a three-dimensional image of a protein at atomic resolution. This breakthrough proved the technology's potential. " Joachim Frank  made the technology generally applicable. Between 1975 and 1986  he  developed an image processing method in which the electron microscope's fuzzy twodimensional images are analysed and merged to reveal a sharp three-dimensional structure. "Jacques Dubochet added water to electron microscopy. Liquid water evaporates in the electron microscope's vacuum  which makes the biomolecules collapse. In the early 1980s  Dubochet succeeded in vitrifying water â  he  cooled water so rapidly that it solidified in its liquid form around a biological sample  allowing the biomolecules to retain their natural shape even in a vacuum."

Example Input: What is the sentiment of the following document towards the entity Rex Ryan Monday ? FOXBOROUGH  Mass. - In one sentence  Rex Ryan managed to compliment and challenge Bill Belichick at the same time.
 The achievement is no surprise  considering the New York Jets coach can create headlines just by speaking. While his most recent comments about Belichick may have raised some eyebrows  they didn't shock the Patriots coach.
 Last year  Ryan said he didn't plan to kiss Belichick's rings  and Newsday's Bob Glauber asked Ryan Monday if he had backed off since making the statement last year. Ryan gave an honest response.
 "I just told the truth " Ryan said. "I came here to win. As much as I respect and admire Bill Belichick  I came here to kick his ass  and that's the truth. That's just the way it is."
 The coaches may have different approaches  but they continue to publicly praise each other. While Ryan is focused on beating Belichick  he went on to talk about his respect for Belichick.
 "I came here to beat him  and I'm never going to backtrack on that " Ryan said. "I do respect him and all that  absolutely. But he's the one to beat.
 "I recognize that he's the best coach in football  and he still is. But that doesn't mean I'm not going to try to go beat him  because you're darn right I'm trying to beat him  without question. He's going to get my best."
 Belichick also had praise for what Ryan has accomplished.
 "I think he's an excellent coach " Belichick said. "He did a great job at Baltimore  whether it says defensive line coach or defensive coordinator down there.
 "He's doing the same thing with the Jets. Took them to the AFC Championship game last year. Got a great record this year.
 "So he's a good football coach. His teams play hard. They're obviously well-coached. They handle pressure. They play with a lot of confidence. He's done an excellent job."

Example Input: What is the sentiment of the following document towards the entity Rabbo Mansour Hadi ? This weekend's bloodshed broke out Sunday in the southern port city of Aden  where forces loyal to the separatist Southern Transitional Council traded gunfire with loyalists of  President Abed Rabbo Mansour Hadi . The scattered fighting has claimed at least 12 lives and injured scores more.
The two sides had shared an uneasy alliance since 2014  when they were united in their opposition to the Houthi rebels who seized cities in the country's northwest  including the capital  Sanaa. Together  the STC and  Hadi 's forces managed to repel the Houthis from Yemen's southern governates and Aden  the large city where Hadi's government had presided since its ouster from the capital.
As Reuters notes  the fighting follows the expiration of a deadline set last week by the southern separatists. Irate at what they call corruption and the deep erosion of public services in the areas still governed by Hadi  the STC had delivered him an ultimatum: shake up the cabinet and sack bin Daghir or face ouster. That deadline came and went without sign that  Hadi  had any intention of complying.
The new fault that has opened between  Hadi  and  his  erstwhile allies in the STC adds another dimension to a war already packed with a dizzying array of players â and a long  tortuous history dating back at least to 1990. That's when South Yemen  a formerly independent state with Aden for its capital  agreed to unification with its northern counterpart. The union has never quite been an easy one  strained by a 1994 civil war and more recently  calls for greater autonomy in the south.
Add to that latent friction the bloodshed of recent years  which has seen Yemen's internal conflicts take on the character of a proxy war among competing powers in the Gulf region. The Houthis  a Shiite group based in the northwest  have been backed by Iran  while Saudi Arabia has led a coalition conducting an air campaign since 2015 supporting  Hadi  and  his  Sunni allies.
