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: 'Water if very important to me as well. I'm on a medication where I get dehydrated very quickly and I need to make sure that I'm properly hydrated at all times. ' 'Well that is going to be a problem then because I have a medical condition too. How can we meet in the middle? I get 2 water, 2 food and no firewood?' 'I really need that water. I'm going camping in the desert where firewood will be vital for me as well. How about I take 2 water, 2 firewood and you get 1 water, 1 firewood and all the extra food?'
Utterance: 'That works. Deal🙂'

Answer: No


Question: Context: 'I could manage with one firewood and two foods, but if you have canteens for everyone, may I then have all three waters? I had planned to collect water from the river, but I'm worried I may get sick.' 'you pointed out that we will need more!  😮 i will take 2 waters' 'I didn't know you had supplied everyone with water before the trip. I was merely trying to look out for your needs, but you said you didn't need them!'
Utterance: 'I am giving you a lot of food. You are being unreasonable and backtracking. You are getting some of everything with my offers, and there are only two of you.'

Answer: Yes


Question: Context: 'I was thinking we can say which ones we want more? Or depending on where we are camping and our camping abilities, we might need some materials more over others' 'That sounds good to me!  I heard where we are going it is going to be really cold the next couple of nights so we definitely need extra firewood.  We also have a pretty big group so extra food and water would come in handy too.  So how about I take 2 of the extra firewood, 1 extra water and 2 extra food?' 'Oh we have a substantial group as well, one of which is newly pregnant. Since we could find firewood ourselves, how about you take 2 firewood, 1 water, 1 food? '
Utterance: 'We could really use that extra water and food, maybe you would be interested a little bit more firewood?  How about I take 1 firewood, 2 water, and 2 food?  I've got a big group of guys to feed.'

Answer:
Yes
