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: '😮Sound good enough but since you know i can not do without having anything to sustain me whenever i am thirsty then i suggest you are free to take TWO of the water and since your food has also been stolen by bears and you don't make much left, then you can have the TWO of the food items too and leave the THREE firewood for me with ONE food. How does that sound? 🙂' 'I think we are getting very close to a good deal. Would you be willing to give me ONE firewood in case the stuff I have gets wet?' 'I strongly agree and shall we call it a deal now? 🙂'
Utterance: 'Like I said, we are close but I really would feel better with just one of the firewood. I'm afraid of not being able to build a fire. If you really need the firewood, however, then I would take one additional item of EITHER the water or food instead.'
answer:
Yes


question:
Context: 'Hi fellow camper! What are your needs for the extra provisions.' 'Hi i'm really excited for camping. I am looking for food and water ' 'Yes, a much needed getaway. Oh my, we need the same provisions! How would you be with receiving two waters, one food package, and two of the firewood?'
Utterance: 'I think I would be able to make that work. What are you looking forward to while camping? '
answer:
No


question:
Context: 'fair enough, how do you want to split the water' 'I'm willing to trade off water if you need more of it! I'm really looking for food and firewood, but I'll take food over wood.' 'sounds good, how about i take 2 firewood, and 2 waters, and one food'
Utterance: 'Hmm if I give you two firewood, how much food will I get back? I'm only willing to do two for two.'
answer:

No
