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.

Context: 'sure that sounds fair' 'Ok, do you have any interest in any fire wood?' 'I do need firewood, we cook over open flames. 😮How you get 2 water, 1 food and 1 firewood?'
Utterance: 'How about if I give you 3 food for 3 waters, and then we split the firewood?'
No

Context: 'I need firewood, because I have a medical condition that causes my veins to close if I get too cold at night. I don't mind sharing the water.' 'I could give you 1 firewood, 2 waters, and 1 food. ' 'If you make it two food, we have a deal.'
Utterance: 'I would rather let you have the third water than other food. I don't like fish. ☹️'
No

Context: 'I’m doing fine. How about you?' 'I'm doing well. I was hoping I could have the extra firewood because my group decided to camp for a few extra days and want to make sure we have enough' 'How many of you are on the camping grounds?'
Utterance: 'It's just my family. There are 6 of us total'

Yes
