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.

'but thats the only offer im willing to give'
Utterance: 'Well then unfortunately I think we're gonna have to walk away from this and neither of us gets anything we could both use.. that's unfortunate and I'm sorry to see it end in such a less than magnanimous fashion ☹️'
