instruction:
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 self-need strategy, otherwise output No. self-need is a selfish negotiation strategy. It is used to create a personal need for an item in the negotiation, such as by pointing out that the participant sweats a lot to show preference towards water packages.
question:
Context: 'I am allergic to tea and coffee. I wonder if the smaller fire would be more quaint for everyone to sit around. ' 'It really wouldn't do the job that well at all.  You could always prepare hot cocoa or use your share of the food to make a warm stew.  I really do need at least the two firewood and a couple of food.  You can have all the water to make a hearty and hot stew to get your through the night, though.' 'I can't eat much anyway because of the health issues. You could have all of the food if I could get the extra firewood. That would still give you an extra firewood in addition to the basic supply and lots of extra food for your party. I'm sure they would love having some of the stew you mentioned.'
Utterance: 'Well, how about I take just the one extra firewood, plus all of the food, and one of the water so that I can make stew?  Would that work for you?'
answer:
No


question:
Context: 'I am going camping too.  May I ask where you are going canoe camping?' 'We are going to camp in Oregon.  We are looking forward to it.  The views and scenery should be gorgeous.  How about you?' 'I am going to the Allegheny mountains in Pennsylvania.  I'm going to be hiking a lot so I will need some extra food.  Let's balance out the food and water somehow....'
Utterance: 'Sounds good.  We will also be hiking a bunch and I have little kids who go through water and food like crazy.'
answer:
No


question:
Context: 'I'm going hiking, and I really need food, it works up an appetite.' 'Well I didn''t bring any with me so I really need two.  I am willing to give you 2 waters.🙂' 'I also need the water, because it's not safe to drink from streams here.  '
Utterance: 'You are right, my water is dirty also but I am willing to let you have all three water. I would rather eat, so I would like 2 food.'
answer:

Yes
