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: 'Which supplies do you need?' 'Well, I really need water in case we get really thirsty from hiking. I also need firewood in case it gets colder and we need more. It would be cool to have more food added for dessert like s'mores, but it's not really necessary.' 'How about you take all the water and one of the firewoods, and I can have all the food and 2 of the firewoods'
Utterance: 'Let me think about it. What supplies do you need?'
