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.

Context: 'k i need food as first priority' 'Unacceptable' 'why'
Utterance: 'I require the majority of food as I have explained.'
No

Context: 'Well I don't mind either way about the food. I'll recommend giving you 2 firewood 1 food and 1 water. ' 'how about you get 3 waters and 2 foods? Does that work better?' 'yes how much firewood. I need at least 1 to cook the food.'
Utterance: 'you should have enough firewood in the basic supplies to cook the food i think, with three waters and 2 foods you get 5 items and i get 4'
Yes

Context: 'I understand. I am unfortunately sick and need the warmth of the fire and water to take my medication or I will die very soon' 'You can have all of the firewood, we just need 1 water ' 'That is fair. Could I also have 1 food so I do not starve'
Utterance: 'what about your basic food rations?'
Yes
