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.
One example is below.
Q: Context: 'Well maybe we can work something out between us.  Our food and water was in the bags they loss so I really need those.  Do you think you could make do with 1 food and some water?' 'I really need 2 foods. I can do with 1 water or if you are in a giving mood then maybe I can have 2 waters?' 'Looks like we both really need the food.  If you get 2 food I would need 1 food, 2 water and 3 firewood. '
Utterance: 'Since you will get all the fire would do you think I could have 2 foods and 2 waters. You would get 1 food, 1 water, and 3 firewood. You seem like you are a great outdoor person that I would think you would be able to catch some fish to cook with the firewood.'
A: Yes
Rationale: Correct. The participant tries to undermine their opponent's needs by mentioning that the opponent can just fish for food.
Q: Context: 'That's amazing!!!  So here is the deal...I'll give you the 2 firewood packages so you can sleep under the stars tonight.  In return I'll have to keep 2 water packages and 2 food packages since I won't be able to cook all of this fish and I still have a family to feed.  ' 'I'm glad you understand my problem. But I really need those 3 firewood packages. I'd be happy to give you 2 water packages and all the food in exchange.' 'Initially you were willing to take the 2 packages of firewood. If you have all three I won't be able to cook any of this fish and it will all go to waste. ☹️'
Utterance: 'Didn't you bring any firewood at all with you?'
A:
Yes
