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: 'Splitting the food is what I was thinking as well, but I'd also like to split the firewood. We can split the water or I'm fine taking all of that.' 'I would be willing to take 2 firewood, 3 food, and 1 water if that would work for you.  ' 'Hmm I think I should take 2 food, 1 firewood, and 3 water. What do you think?'
Utterance: 'Is your first priority the water?  I'm definitely willing to split up by what is most important to us both.'

A: No

'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!'
