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.

Utterance: 'Would you be willing to trade a piece of firewood for an extra water bottle? That will save me some time from chopping down extra wood.'

Context: 'Hello.' 'Can i kindly know your preferences please?' 'Well, I'm kind of low on water, so I'd like to get as much of that as I can. I'd like to go hiking and I don't really have enough water for a long trip. What about you?'
Utterance: 'Ohh nice.I also have the same issue around here.The thirst for water is growing high than ever due to drought'
