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 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: 'I would give you all of the additional food if you gave me all of the additional water. ' 'That sounds like a deal' 'Shall we divide the firewood two to one? '
Utterance: 'sure as long as I am getting two wood.   It gets very cold at night where I go camping'
answer:
Yes


question:
Context: 'That sounds reasonable. I don't particularly need the food because I see that as more of a luxury but I could really use some more water. It's supposed to get really really hot on the weekend. 😮' 'I hear that. What do you think of if I take 3 of the food supplies and you can have two waters? ' 'That sounds like a fair compromise. I can get food by hunting animals, old school style. That would give you 4 total items. In that case it's only fair if I take all 3 of the firewood. 4 for me and 4 for you sounds like a good deal to me. 🙂'
Utterance: 'That sounds fair to me! I don't know the first thing about hunting so that would be a relief on me. We took a bunch of blankets so we'll be good on firewood.  🙂'
answer:

Yes
