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: 'Hi there! How are you today?' 'Good! How are you?'
Utterance: 'I'm doing well! Almost ready for my camping trip. Need some more supplies though.'
[EX A]: No

[EX Q]: Context: 'I would be willing to take 2 firewood, 3 food, and 1 water if that would work for you. ' 'Hmm I think I should take 2 food, 1 firewood, and 3 water. What do you think?' 'Is your first priority the water? I'm definitely willing to split up by what is most important to us both.'
Utterance: 'Food is actually my first priority but since it seems to be first priority for us both I thought we could split that. Water doesn't seem to be a priority for you so thought I could take that'
[EX A]: Yes

[EX Q]: Context: 'I am really bad at cooking so will probably need an extra good just because I'll ruin one of the 3. Plus Im bringing 2 dogs they can eat the bad food I make 😮 I dont plan on hiking much so how bought I keep all 3 foods, and you keep all 3 waters and we can split the firewood. 2 for me, 1 for you. Great deal!' 'i too i am bad at cooking and i will spend a longer time in the woods so i will need atleast 2 foods, 2 firewood and 1 water' 'But I have more mouths to feed here so I will give you one of the foods, but then need 2 firewood and then take back 1 of the waters. '
Utterance: 'your dogs could probably hunt for something for you guys. and i would be in the would for a very long time '
