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: 'Actually, I think I may need more food than water. How about I take the food and we can split the water. You may have 2 waters, if you need them.' 'Sure then. You can take all the food. It's not really a priority to me. ' 'Great. So if I have three food and one water, you can have three firewood and two water. Would that work for your trip?'
Utterance: 'That's perfect for my camping trip. '
answer:
No


question:
Context: 'Interesting - you're essentially saying that you need the majority of two of the three items. Hmm...' 'Yes, thats all. I need 1/3 food, 2/3 water, and 2/3 firewood.' 'Still not convinced in any way that you need more items in total over me. Please clarify!'
Utterance: 'Food is what I prioritize much more than the others. If you want the majority of the others, I will need all the food.'
answer:
No


question:
Context: 'I can give out the food in exchange for the firewood' 'Okay. I need all of the water, if you're getting the firewood. ' 'I can't give out all the water. I need to be hydrated as well. '
Utterance: 'You already have all the basics, though, so you won't lack sufficient water to be hydrated. I have a serious medical condition that requires that I have access to additional water. '
answer:

Yes
