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.

Utterance: 'Hello, how are you? 🙂'

No


question:
Context: 'I will be camping for 3 day so I gotta have some food.  Although, I do understand your situation.' 'I see. Yeah, if any of us knew how to fish or forage, we wouldn't need as much, but we're all from the city, so our survival skills are pretty bad and we're going to be camping for almost a week. But I get that fish aren't super reliable for food either... ☹️' 'I understand.  So we have came to an agreement that I get 2 water, 1 firewood, and 1 food, is that right?'
Utterance: 'Yeah, that sounds good to me. Thanks for being understanding. I hope your camping trip goes well.'
answer:
No


question:
Context: 'It should be a good weekedn for it.  Unfortuately the air;ine loss our luggage with the sleeping bags and food.  Not a good start for us with my mother-in-law along for the first time.  My wife and her is down getting trail maps while I sort out keeping warm tonight and feed after some hiking.' 'Oh no! That sounds like a problem. I have four kids so I can relate about the concerns for staying warm and having enough food.' 'I see they have some supplies here to share between the camp sites.  Maybe we can divide up the supplies so it works for both of us.  I can really use 2 wood and 2 food.  What about yourself?🙂'
Utterance: 'I think food is pretty important for you, so I'm ok with you having 2 food and I'll take 1 food. Since you get more food I think it's only fair I get 2 firewood while you take 1. You can collect more firewood along the way. I didn't have room to pack firewood either with our smaller car.'
answer:

Yes
