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: 'I do need some myself as well' 'I suppose it is important - we'll definitely have split that up somehow. ' 'Well how about this. I take all the Food, and 1 Water. You get all the Firewood and 2 Water.'
Utterance: 'we're definitely thinking alike - That extra water would go a long way to keep us safe and comfortable'
A: 
Yes
