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.

[EX Q]: Context: 'Yes I think that sounds fair.' 'So if I take 2 foods and 1 firewood, you take 1 food and 2 firewood. What would be fair for water?' 'What if I take two waters and you take one water then?'
Utterance: 'I think that sounds fair, since you compromised on food. Sounds like a deal!'
[EX A]: No

[EX Q]: Context: 'That is fine since there are 3 wood and I want 1. ' 'Then it is good deal.  I need two wood, 1 food, and 1 water.' 'I really need all the food, I have a lot of people to feed'
Utterance: 'I will provide you the food, but I am asking only one for my people.'
[EX A]: Yes

[EX Q]: Context: 'I have a medical condition that causes my veins to close up when I get too cold. I will thus need the 3 firewood.'
Utterance: '☹️Oh, that sounds awful. Are you sure you need all three packages of firewood?'
[EX A]:
Yes
