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.

Question: Context: 'I don't want to be too hungry either but I think perhaps I might need an extra water to compensate for the lack of food.' 'Since I am giving you all of the firewood that you said was most important to you, I feel I should get at least the same amount of items as you, especially since you are getting exactly the firewood you want. I will need to stick to three waters and two food.' 'The firewood is most important to me to be sure. However, if you get more food and all of the water I could end up going hungry.☹️'
Utterance: 'Well I would be happy to exchange you one of your firewood for the one water you need. That way you won't go thirsty.'

Answer: Yes


Question: Context: 'how am i supposed to stay alive with one package of food and water im fat lol' 'I don't think you that fat, your lipids will help you stay warm and full out there, haha' 'Im not as good at you at foraginf for food and water i probably dont have the experience as you do being in the outdoors and living off the land.🙂'
Utterance: 'With the extra firewood, you can hunt for fish and other animals outside to thrive'

Answer: Yes


Question: Context: 'Would you be willing to take more firewood for less food?' '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?'
Utterance: 'What if I take two waters and you take one water then?'

Answer:
No
