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 other-need strategy, otherwise output No. other-need is a selfish negotiation strategy. It is used when the participants discuss a need for someone else rather than themselves. For instance, describing the need for firewood to keep the kids warm.

Q: Context: 'Oh that sounds awesome. I am actually going camping with my grandparents and my children. So I would love to have 2 firewoods for them. They get cold easily so I would like a little extra to make sure they can stay warm throughout the evening. 🙂' 'Yes, I would love to give you two firewoods! 🙂 My grandparents might check in on us, they like camping. But my grandpa has rheumatic problems so he needs lots of water. Could we take all three?' 'Thank you for the two firewoods. I totally understand that. Since we do have young children I want to make sure they stay hydrated so I would be willing to give you two if I can just have on extra for them.'
Utterance: 'OK. Your children must be hungry, could we give them two food while we keep one?'

A: Yes
