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: 'It was going great until a bear came and took all of our food 😮' 'Oh no, that's not good.  I still have some left over, but we're running out of firewood to use to heat it.' 'Seems like we are in the same boat, the bear tore our tent to shreds so we are sleeping outside and it is cold☹️'
Utterance: 'Sounds like a rough camping trip.  It has been pretty cold lately.'
answer:
No


question:
Context: 'Well that is not going to work well for my family of 8 now is it? Haha. I think we can come to some sort of agreement though.🙂' 'What do you propose?' 'I really need food too, but I am willing to deal and let my kids go hungry I guess ☹️ I propose I get one food, 3 firewood and 1 water.  '
Utterance: 'Will you please give me one firewood? I may run out of what i have. Just one.'
answer:
Yes


question:
Context: 'You'll have some water, this is for extra.  Would you take 2 packages of food and 3 packages of firewood in exchange for me getting 3 packages of water and 1 package of food?' 'Yes, I would.' 'And you can use your extra firewood to purify any water you find as well while you're already enjoying the fire.'
Utterance: 'That's true.  Thanks for the suggestion🙂'

No
