TASK DEFINITION: The input is taken from a negotiation between two participants who take the role of campsite neighbors and negotiate for Food, Water, and Firewood packages, based on their individual preferences and requirements. Given an utterance and recent dialogue context containing past 3 utterances (wherever available), output Yes if the utterance contains the uv-part strategy, otherwise output No. uv-part is a selfish negotiation strategy. It is used to undermine the requirements of the opponent. For instance, suggesting that the opponent would not need more firewood since they already have the basic supplies or a suggestion that there might be a store near the campsite where the opponent can get the supplies instead.
PROBLEM: Context: 'If you boil the water above the fire, it will provide additional heat over time.  You would also be able to make tea, which would warm you up from the inside as well, better than any fire would.  That would probably be most beneficial to you.  I really do need the 2 firewood if there's any chance of making a bonfire for my party.' 'I am allergic to tea and coffee. I wonder if the smaller fire would be more quaint for everyone to sit around. ' 'It really wouldn't do the job that well at all.  You could always prepare hot cocoa or use your share of the food to make a warm stew.  I really do need at least the two firewood and a couple of food.  You can have all the water to make a hearty and hot stew to get your through the night, though.'
Utterance: 'I can't eat much anyway because of the health issues. You could have all of the food if I could get the extra firewood. That would still give you an extra firewood in addition to the basic supply and lots of extra food for your party. I'm sure they would love having some of the stew you mentioned.'

SOLUTION: Yes

PROBLEM: Context: 'I'm doing great!  I'm on the first camping trip with my five children.' 'Wow, that's amazing. My parents took me camping when I was young. Now we going hiking every other weekend. What do you plan on doing?' 'That sounds like so much fun!  I hope we get to hike some.  I have my four month old baby with us which is exciting.  I'm worried I didn't bring enough water for his bottles, though.'
Utterance: 'That sucks, you need to be hydrated. What supplies do you require? My family loves to grill, so we do require food.'

SOLUTION: No

PROBLEM: Context: 'Yes same to you. I am very excited to be going on this trip cannot wait to start hiking. Do you have any plans for yours?' 'Yes we (my boyfriend daughter and I) want to go to the mountain top its not going to be easy with this weather but we will make it how about YOu?' 'We want to hike along the trails near the river! We will need lots of food to keep us going '
Utterance: 'I understand that atleast you are going to be close to water, that will be our most important thing since we will be thirsty and you know kids and trying to tell them to ration the water...LOL'

SOLUTION:
Yes
