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: '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: 'Hello' 'Hi there!'
Utterance: 'Im really low in food, is it ok if I get 3 Food, 1 water & 1 firewood? What do you think?'

SOLUTION: No

PROBLEM: Context: 'Hey there how are you?' 'I am fine friend. I need a lot of firewood though. It is freezing'
Utterance: 'I definitely need firewood as well. We didn't anticipate it being as freezing cold as it is at night. There isn't much around us. We've also been using a lot of water, which we could use more of since we've been looking for firewood.'

SOLUTION:
No
