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 think the fairest thing would be that you keep 1 water, 2 food, 2 firewood' 'How about I take 2 water, 2 firewood, and 2 food, and then you take the rest' 'Let's stay like this, 2 of water, 1 of food, 1 of firewood and you take the rest'
Utterance: 'I really need the water more than the rest of that stuff. I'll take 2 waters, 1 food, and 1 firewood. '
answer:
Yes


question:
Context: 'I would give you all of the additional food if you gave me all of the additional water. ' 'That sounds like a deal' 'Shall we divide the firewood two to one? '
Utterance: 'sure as long as I am getting two wood.   It gets very cold at night where I go camping'
answer:
Yes


question:
Context: 'Hello I'm really hungry and thirsty and want some food and water if that's ok with you. ' 'Well some is okay but not all. The thing is that we left in a hurry and forgot to pick up the bag with the extra food items. I am sorry but we have kids with us so we will need the food. Am sure you understand ☹️' 'Fair enough I understand that you have hungry kids. If I give you the majority of food can I get a majority of the other two items?'
Utterance: 'Well, what if I take all food and 1 water and you take the rest. Will that work for you? we do have enough firewood.'
answer:

No
