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: 'so I would have 2 water, 2 food and 1 firewood? My kids were looking forward to making s'mores. If I could get 2 water, 2 firewood and one food, that would be great!' 'You would get 2 water and 2 food, I would get 1 water and 1 food for hiking and 3 firewood for having to stay out longer in the dark to complete my hiking goals.' 'doesn't really seem fair for you to get all the firewood. I would like to have at least one because then we're completely in the dark.'
Utterance: 'You get lots of water and food for your children, I am cutting back on my goals by giving up energy which means I have spend more time outside hiking.  I do need to stay warm'
answer:
Yes


question:
Context: 'hi there! 🙂' 'Hello.'
Utterance: 'I'm excited for camping! We have these extra items. What do you need most of?'
answer:
No


question:
Context: 'It sure is..So how much food do you need for the trip? Do you need firewood to cook the food? Thank you for understanding my issues. 🙂' 'I definitely need the food the most. I'm definitely not a "hunter", so if I were to run out, I'd be in pretty sad shape. I do need the firewood for both cooking, and keeping warm. It gets cold at night where we're going. How about youself?' 'Well since we were already given a few supplies before this deal, I was wondering if you could give me all 3 water, and I could give you all the firewood and 2 of the food packages. I only say all the water because we already have some and my medical condition sucks. lol I wish we could camp together! we seem to be a good match. lol! 🙂'
Utterance: 'I wish that too 🙂 And I 100 percent understand the need for water, but I don't know if I can go with only what I have so far. What if I only took 1 water, and you take 2? I hate to take any because I do understand you need it, but I really can't go without any  ☹️'
answer:

Yes
