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.

[Q]: Context: 'I am glad you accepted. I really need it.' 'I will take all the food and water then' 'That will be very unfair of you. How am i going to survive without water or food?'
Utterance: 'You have food and water, this is just extra supplies'
[A]: Yes

[Q]: Context: 'I would be open to that if you could give me three packages of water 🙂' 'Hmmm...I'm pretty muddy due to clumsiness, so I may need one extra. I could give you two waters and all of the firewood. What do you think? 🙂' 'So are you suggesting that I would get 2 waters, 3 firewood, and no food?'
Utterance: 'Right! Well, beyond the food you already have. '
[A]: Yes

[Q]: Context: 'Hi! I'm super excited to go camping with my family as a great way to vacation due to Covid19. My kid is so restless from being cooped up in the house all the time. Are you planning on going camping too?' 'I am! It is the perfect way to get away and still manage to social distance! I am worried about having enough water though, are you short on any supplies?'
Utterance: 'I think I'm good. I'm not 100% sure. My husband likes to do adventures on the fly. He got these water filter straw thingies from Amazon and said that if we run out of the water I packed, that we can drink the water in the lake but I don't really trust the straws.'
[A]:
No
