Definition: 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.
Input: Context: 'Yes, does that work for you.  I could give you 1 water and 2 foods as I really need the water for my hike.  I tend to overheat easily. ' 'You are flipping it around. I can't give you 2 water and 2 firewood as that wouldn't really be fair ' 'Okay, how about if I give you 3 foods and you give me the 2 firewoods and 2 waters?'
Utterance: 'THanks, but I really need the water. I thought you would enjoy the food with so  many guests in your campsite. Is that a possibility?'

No
