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: 'I do need some food. I would like to get at least 1 food. You can still get 3 firewood.' 'I could use water as well, so I could get 1 water, 2 food and 2 firewood' 'I am good at making fire and have a starter so I can give up all the wood.'
Utterance: 'I still need 1 water, don't have a water purify kit. ☹️'
[EX A]: No

[EX Q]: Context: 'I get tired to easy so I probably won't be much fun at a bonfire ☹️. I really do appreciate the offer though. I would think the extra food would do you more good for your party. ' 'The extra food would be appreciated.  How about if I take just two each of the firewood and food, and you can have the remainder, plus all of the water?' 'I am just concerned that only 1 firewood might make it so I'm too cold to function. '
Utterance: 'If you boil the water above the fire, it will provide additional heat over time.  You would also be able to make tea, which would warm you up from the inside as well, better than any fire would.  That would probably be most beneficial to you.  I really do need the 2 firewood if there's any chance of making a bonfire for my party.'
[EX A]: Yes

[EX Q]: Context: 'I could really use the firewood too, it will be very cold where we are going. Since it will be cold, we will not be drinking much water. How about 2 firewood for you, 3 food for me?, ' 'May I ask how many are going camping with you, i would agree, but the needs of children are different than adults. I will need at least 1 food, to ensure I have enough for the kids. ' 'We will have 50 adults with us. How about 2 firewood, 1 food, 1 water for you?🙂'
Utterance: 'lots of work for the both of us, at least you will have lots of help on you end. I accept the 2 firewood specially if you have elderly with you. will you be okay if give me 2 foods? '
[EX A]:
Yes
