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: 'Hello' 'Hi there.. how are you doing today?  I hope well!  🙂  So, it looks like we need to divy up these supplies, huh?  Do you have any thoughts on the issue?'
Utterance: 'I'm doing fine thank you, how about you? Well for my trip I'm most interesting in socializing so a great campfire a night would be great, I'd prefer not to boil water either so want extra of that too. Food less so as I will go fishing and know wild vegetables, fruits and mushrooms I can pick. How about you?'
answer:
Yes


question:
Context: 'Same here. My kids are really looking forward to this. What is most important to you?' 'Firewood! I need it to cook my food and also to stay warm. What about you?' 'That is the same for me as well. My kids were really looking forward to making s'mores and telling stories by the campfire. That's all they've been talking about'
Utterance: 'Awesome, I'd be happy to negotiate that. What is your second most needed item?'
answer:
No


question:
Context: 'My main objective for the camp is water, since I have a large family and the amount of water they give in the camp is very small for all my family.' 'I need water also but firewood is my second highest priority item. Maybe you could take more of the water and I could take more of the firewood.' 'I find it a good deal, however before making a deal, I like to talk to people, get to know them better. I plan to go to camp with my family: my wife, my four children and myself. Are you going with your family?'
Utterance: 'Yes, I am going with my wife and two teenage sons. We are planning on doing a lot of fishing!'
answer:

No
