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.

Ex Input:
Context: 'That does not seem entirely fare but I need more water so I will take this deal' 'It's honestly not that fair to me either, but sometimes we just end up with slightly conflicting priorities in life.  🙂  I think making the best of the situation is the way forward.' 'Yeah, That's true,🙂, so do we have a deal?'
Utterance: 'Yup, the food to me, the water to you, and 2 of the firewood to me, 1 to you is as I understand it!'

Ex Output:
No
