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.

Question: Context: 'I would be OK with two packages of water.' 'Good. 2 packages of wood for me. 1 for you. 2 packages of water for you, and one for me. How should we divide the food?' 'I will take 2 packages of food and 1 for you.'
Utterance: '😮I thought you didn't need so much food, because of your diet....'

Answer: Yes


Question: Context: 'I can't wait 🙂 Let's talk about these supplies. I've got hungry mouths to feed, Can I take the food and you can have half the firewood and all the water?' 'Hmm, I need food too. I am willing to split. I will give you 2 food since you claimed it first. Can I have 2 waters then?' 'That's fair, but I have wiggle room on the water, how about I take two food, two firewood and you take 3 water, 1 food, 1 firewood?'
Utterance: 'Is there anyway you will go with that I get two firewood? I need food the most but since you get most of that can I get most of the firewood? So 1 food, 2 firewood, and 2 water for me?'

Answer: Yes


Question: Context: 'I tend to get dehydrated quickly so if I don't have enough to drink I won't be able to provide everyone with food.' 'Well, we have extra food too. How about I take 2 water, 1 food, and give the res (1 water, 2 food, 3 firewood) to you?' 'That's super thoughtful of you. However, I really need two waters so I can provide for everyone. Once we have enough food and fire we can always go get water from the stream and boil it for the kids.'
Utterance: 'Of course there is no garuntee you will catch anything, if you want 2 waters I'd prefer to take all the food just in case'

Answer:
No
