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 Input:
Context: 'That may be possible.... 🙂 What did you have in mind for the food replacement? ' 'You can have all the water if we can have all the food?' 'I dont think I am okay with that ☹️. Food is essential to our groups morale when camping. We would like 1 additional food preferably.'
Utterance: 'Well you guys did say you did not care much about large fires. What if you gave all the firewood in replace for the water and you can still keep 1 food?'

Ex Output:
Yes


Ex Input:
Context: 'I can't give out all the water. I need to be hydrated as well. ' 'You already have all the basics, though, so you won't lack sufficient water to be hydrated. I have a serious medical condition that requires that I have access to additional water. ' 'The maximum bundle I can give is all packages of food + 1 package of water'
Utterance: 'Sorry, that won't work for me. I've already said that I have a medical condition that requires additional water. You do not need that much water just to be hydrated -- you already have basic water. I can give you all of the firewood, but I need all of the water. '

Ex Output:
Yes


Ex Input:
Context: 'I like the sound of getting the firewood, but I can't just accept no food or water.' 'I'll give you one of the extra food so you have a little extra to cook for everyone but I'm really gonna need all that extra water, it's going to be really hot this weekend and the folks at the capsite get to sit in the shade all day' 'Now we are making progress. But come on, I will need at least one water to make sure I'm hydrated. I wouldn't want to get heatstroke out in the woods.'
Utterance: 'The basic supplies include water, the additional supplies are just extra. Plus I think there's a well nearby!'

Ex Output:

Yes
