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: 'Then you get two food and no firewood here.😮' 'You mean you can't let up one firewood for me?' 'Not this time, I really need all the firewood and food is a large need for my family of 8. We need the firewood to cook all our meals from the animals we hunt since we are short on food.'
Utterance: 'But these are only additional packages☹️'

A: Yes

Q: Context: 'I would love to have the Firewood the most. ' 'Unfortunately I need firewood the most too. How about I take 2 firewood, 2 food, and 1 water?' 'I feel that I am not getting a fair deal. '
Utterance: 'Then what do you think is fair?'

A: No

Q: Context: 'I am going to be camping for a couple of weeks, so I will need quite a bit. I also realized some additional water would be good, because I have some meals that need me to boil water. Maybe you can have 2 firewood in exchange for me having one of your waters? Then you would still have plenty of water, but also plenty of firewood 🙂' 'So sorry, I just realized you did not agree to the 3 waters in exchange of 3 foods. if you want a water, i will also will need one food. just to make things more fair on my end. If not i am looking at 2 waters, 0 foods, and 1 firewood. But i am willing to compromise for 3 waters, 1 firewood, and 0 foods. and you'll get 3 foods, 2 firewoods, and 0 waters, what do you think?' ' I appreciate your willingness to discuss this, so we both get a fair deal. I would really like if I get 3 food, 1 water, and 1 firewood. Then you would get 2 water and 2 firewood. You said that you really need water and food, so I think that would work best for both of us to get what we need most. What do you think? 🙂'
Utterance: 'Np, problem, water is high in demand on my end with the amount of kiddos I am taking. Water is my main concern, will you be okay with 3 Foods, 2 Firewoods and no water?'

A:
No
