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.

Context: 'Me too! im bringing my 5 month old baby with me and im worried im not gonna be able to find purified water for his formula!' 'Ah, Baby's first camping trip. 🙂 But that is a bit of a big worry. ' 'Yea so I was hoping i could get 3 of the waters if possible and 1 firewood and you can have the rest!'
Utterance: 'I really wish I could take you up on that offer but I could really use some of that water as well. Perhaps, I can get one water while I'll give you some extra food.'
Yes
