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: 'That make sense. I need firewood though too because I have an autoimmune disease. When it flares up - when it gets too cold - I get very sick and have to go to the hospital. I need to make sure I have enough for the trip as well. I need food to keep my metabolism up so I can make sure my disease stays in check. Why do you want food?' 'That makes sense . I have a friend coming with me on the camping trip, and she also needs to eat, so I'd like to get an extra package of food if possible. ' 'Okay that would be fine. If I can have 3 packages of firewood, you can have 2 packages of food. Does that work?'
Utterance: 'That does not work for me. I need at least one package of firewood. I'm sure you understand, because it seems like we have medical conditions with similar effects. You can take all of the water if I can get 2 packages of food and 1 of firewood. Does that work?'
answer:
Yes


question:
Context: 'yes we can' 'Ok, could you tell me which item you need more and which one you need less?' 'i will be needing more of water '
Utterance: 'Okay, what I need most is food because I need nutrients, could you tell me what is the least you need?🙂'
answer:
Yes


question:
Context: 'Yes that is totally fine with me. What about firewood' 'I can give you 1 of the firewood. I would like to stay warm at night so I want 2. 😮' 'Hmm that's going to be hard for me because I also get cold. what other reasons do you have?'
Utterance: 'I like to have a big fire so that I can feel good at night. I can get lonely at night. ☹️'
answer:

Yes
