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: 'I can trade more food but I need a bit more water. ' 'I do need the water as well, I can trade more firewood.' 'No I want need at least two packages of water. I can give you two packages of food and all my firewood.'
Utterance: 'Sorr I can give you 1 water only or I would not have enough for myself. '
answer:
Yes

question:
Context: 'Hi, I would like all of the water and 2 food packages. You can have all of the firewood and one food package. Does that sound good?' 'Nice to meet you! I definitely like the idea of having all of the firewood, but water is very important to me. Let's see if we can come to and agreement on how to split up the water.' 'I typically drink a lot of water every day. So I can't agree with much less on that!'
Utterance: 'Alright, I'm sure we can something that works for both of us. The location I'm camping in is only accessible by foot, so I anticipate that I'll need a little more water than normal to feel completely safe. Is there any water source nearby your campsite?'
answer:
Yes

question:
Context: 'I would really like to have 3 waters and 3 firewood because this is my first time camping and I don't have survival skills. ' 'You must be a comedian. We will need to come to a compromise because there's no way that's going to happen. I am like a water buffalo so I'll need at least two waters. In addition, my family is from the South and will need firewood as well.'
Utterance: 'I can't swim too. I think two waters will help me to survive on this trip and I will need at least two firewood to make fish or other food items for my family. '
answer:
Yes
