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: 'I can spare a little as I am currently taking medication that requires me to drink a lot. I can give you 2 bottles of water if you can give me 3 firewood' 'I can't give you all the 3 firewood. We can share them. I can give you 1 firewood? Because I am too scared about dark. ☹️' 'I could give you 1 water for 1 firewood, most of my firewood got wet so is almost useless . Would you perhaps except some food for another unit of firewood?'
Utterance: 'Oh. Let do some deal. If you give me all water bottles I will give you 2 firewood. Can you accept this'

No
