TASK DEFINITION: Given a document, an entity and its sentiment towards the entity, verify if it is the correct sentiment towards the entity. Answer should be yes or no. Note that URLs in the text have been replaced with [Link].
PROBLEM: Verify if the sentiment of the following document towards the entity Jamie Dimon is Negative . Bitcoin's price has fully recovered from  its  recent slump after  JPMorgan CEO Jamie Dimon  called it a fraud and Chinese regulators cracked down on exchanges.
The cryptocurrency had a drawdown of up to 14% in the 10 days after September 12  when  Dimon  compared it to the tulip bubble of the 1600s and vowed to fire traders who used it.
By Thursday  bitcoin had all of the losses. It was up nearly 2% from the lows on the day  Dimon  spoke  at $4157.31 per coin at 10:28 a.m. ET.
The move illustrates bitcoin's wild volatility; it's gained 331% this year  unheard of for any major currency and most financial assets. It also shows why many Wall Street professionals like  Dimon  don't see it as a legitimate store of value but as a speculative instrument.

SOLUTION: no

PROBLEM: Verify if the sentiment of the following document towards the entity Elizabeth Tasker is Positive . Two recent books look at the very human (sometimes all-too-human) process of trying to make sense of the known universe:  The Un-Discovered Islands: An Archipelago of Myths and Mysteries  Phantoms and Fakes  by Malachy Tallack  and The Planet Factory: Exoplanets and the Search for a Second Earth  by Elizabeth Tasker .  They 're so stylistically and scientifically disparate as to seem unrelated  but reading  them  in close succession makes for something greater than the sum of its parts â a joint atlas of human guesses in a world that seems destined to confound us.
 Elizabeth Tasker  knows all about that; The Planet Factory is all about the formation of worlds humanity might never clap eyes on. And if you're hoping for definitive answers about how things work closer to home  think again;  Tasker 's very clear that the scientific method is as often about being proven wrong. "The problem (and there is always a problem)" isn't just an aside on a particular theory  but a thesis for the field. This is a book about trying to map unknown seas in real time; the ghosts of the sailors peering into the dawn looking for Thule live in every telescopic survey.
The Planet Factory can feel intimidating; certainly you must come to it wanting to know everything there is to know about making planets  and hang in there as long as you can before the variables overwhelm you. ( Tasker  offers easy analogies by the handful  and while at first they may seem too easy  you'll appreciate them by the time you're trying to understand the optimum timing of planetary migration.)

PROBLEM: Verify if the sentiment of the following document towards the entity REUTERSPawel Kopczynski Group-IB is Positive . The average amount of money stolen in each of 14 U.S. ATM heists was $500 000 per incident. Losses in Russia averaged $1.2 million per incident  but one bank there managed to catch the attack and return some of the stolen funds   Group-IB  said.
Hackers also stole documentation for OceanSystems’ Fed Link transfer system used by 200 banks in Latin America and the United States   it  said. In addition  they successfully attacked the Russian interbank messaging system known as AW CRB.
Once hackers penetrated targeted banks and financial organizations  they stole internal bank documentation in order to mount future ATM attacks   Group-IB  said. In Russia  the hackers continued to spy on bank networks after break-ins  while at least one U.S. bank had documents robbed twice   it  said.
 Group-IB  said  it  had notified Interpol and Europol in order to assist in law enforcement investigations.
