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: 'No. I won't part with any firewood because I can't stand being cold, and you can have 2 foods if you have a larger group if you give me 1 water. 🙂🙂' 'Sorry, that's not going to work for me.  ☹️ You have a water purifier? Doesn't sound like extra water is necessary.  I am in a hot, dry climate.  I can give up all the firewood to you, if you can leave me the three packages of food.  I would also like 2 waters.  ' 'Sorry but I'm willing to give up all the water for 1 food at least. I already mentioned above that I don't plan on hunting or fishing and I plan on being out for a while. That's my final offer.'
Utterance: 'Okay, I will leave you all the firewood and 1 food, and I will take two food and three water packages. I am willing to finalize that.☹️'
answer:
No


question:
Context: 'so I would have 2 water, 2 food and 1 firewood? My kids were looking forward to making s'mores. If I could get 2 water, 2 firewood and one food, that would be great!' 'You would get 2 water and 2 food, I would get 1 water and 1 food for hiking and 3 firewood for having to stay out longer in the dark to complete my hiking goals.' 'doesn't really seem fair for you to get all the firewood. I would like to have at least one because then we're completely in the dark.'
Utterance: 'You get lots of water and food for your children, I am cutting back on my goals by giving up energy which means I have spend more time outside hiking.  I do need to stay warm'
answer:
Yes


question:
Context: 'hello, how do you suggest we share the items?' 'Hi there! Well first I was wondering what item you think you'd like or need the most?' 'I like firewood and water most'
Utterance: 'Hmm okay, I am willing to give you three waters! I was hoping to get 3 firewood though, as it's going to be really cold where I am going.'
answer:

Yes
