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 have definitely been there before! With taking all the kids I'm worried about them getting dehydrated. I also have a 7 month old that needs water to make her bottles! I was hoping to get 3 extra packaged of water for sure. ' 'That is one of my fears as well. Does you seven month old breast feed? I am hoping for the water as well. I would love to give them to you if I had extra. Is there anything else you need?' 'No they don't ☹️ She is starting to eat a few solid food items. So if I had some extra food that would help. I think if I had 2 waters, 2 food, and 1 firewood to be able to cook and keep things clean I would have enough. '
Utterance: 'I can give you 2 waters, but I would need all the food because my group is bigger. You can have two firewood.'
answer:
Yes


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: 'Sounds good.  We will also be hiking a bunch and I have little kids who go through water and food like crazy.' 'What if I get 2 food packages and 1 water package....and you would get 1 food package and 2 waters?' 'I think we will need more extra food than that.  How about the reverse, I get 2 food and 1 water and you get 1 food and 2 water.'
Utterance: 'I could do that if I could then get 2 packages of wood as well because it's been bitterly cold this time of year at night in the Alleghenies.'
answer:

Yes
