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: 'hi there🙂' 'Hello. How are you today? 🙂' 'Pretty good!  I am looking forward to going on this camping trip with my family.'
Utterance: 'Same here! We had a couple bumps in the road though, as our freezer stopped working so all our food went bad ☹️'

SOLUTION: No

PROBLEM: Context: 'That would be awesome.. I'm looking forward to it.  Glad we could come up to such an amicable and easy arrangement 🙂' 'Indeed, glad we could agree without any fuss. Sure I could catch you some fish too 🙂' 'Rock on.. we love fish.. well at least I do 🙂  Not sure about everyone else.. but if not, oh well, more fish for me 🙂'
Utterance: 'Well if they don't like fish more for us :) So we are 100% agreed now?'

SOLUTION: No

PROBLEM: Context: 'No, I definitely need more water than that for my hikes,  ' 'can i get 3 food, 1 water and 0 firewood then?' 'I think that will work for me.  '
Utterance: 'perfect'

SOLUTION:
No
