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: 'That is really nice of you! I hope they have fun! My family had this trip planned for quite awhile. We have an extra person with us because my son begged me for his friend to come. I couldn't say no. 🙂' '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?'
Utterance: '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. '
answer:
Yes


question:
Context: 'I was just negotiating the water for now.  I was trying to do one at a time.' 'ah, I'm definitely ok with doing one at a time: A 2:1 split is definitely OK with me: The issue is, if we consider each individually, it might be harder to come to a deal, but I'm happy to do it your way.' 'How about you take 1 firewood, I''l take 2 and with food, you can have 2 and I'll take one package.  I have two very hungry boys!'
Utterance: 'Is there a reason you want the 2:1 split? Food my group's largest priority by a large margin (We eat a lot). It's worth a lot more to my group then the firewood would be.'
answer:
Yes


question:
Context: 'Hello, I would like to have three packages of food. We've decided to stay an extra night but need more food to do so.' 'I would be open to that if you could give me three packages of water 🙂'
Utterance: 'Hmmm...I'm pretty muddy due to clumsiness, so I may need one extra. I could give you two waters and all of the firewood. What do you think? 🙂'
answer:

Yes
