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: 'Pretty good, planning my camping trip, checking on supplies.' 'Here too, looks like the weather has changed for us. We won't have enough water to last as we forgot it. Food, we have some snacks, but not enough to get by for our trip. I'm not overly concerned about firewood since it's so hot. But I'm really concerned about water.'
