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.
Example: Context: 'That sounds pretty reasonable as I am in need of firewood the most. Would it be most reasonable to each take what we need most and split the water down the middle?' 'Yes, it would.' 'I think that sounds fair. The problem is that there are 3 waters and one of us would get two and the other one. How should we sort that?'
Utterance: 'You can take the two water. I am not that thirsty most days.'
Example solution: No
Example explanation: In this utterance, the participant does not use self-need since they do not talk about any need for themselves.

Problem: Context: 'ohh that's would be really difficult.However we can still sort things out' 'That is great to hear!🙂 How about you take 2 food, 2 water and 0 firewood? What do you think?' 'uhm.how about i have 3 water 2 foods and zero firewood?'
Utterance: 'Are you willing to budge on one water for me? I have 5 people in my group and they really could use one package of water. It is hot out nowadays. '

Solution: No
