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: 'hello' 'Hello, there. Should we discuss how to divide up the items for the camping trip?' 'yeah. i need 2 firewood, 1 water and 1 food'
Utterance: 'I need to have 2 or 3 pieces of firewood because I did not pack any way to heat up my food without firewood.'
No

Context: 'Okay, I need firewood to stay warm and cook food. I'm willing to give up some water for more firewood.' 'Unfortunately i need the firewood. My body has trouble maintaining heat. I need as much as i can get ☹️' 'Okay, well if you need water and firewood, that only leaves food. If you can part with extra food, here's what I'm proposing'
Utterance: 'Yes you can definitely have all the food. Maybe 2 firewoods and 2 waters for me?'
No

Context: 'Hey there how are you?' 'I am fine friend. I need a lot of firewood though. It is freezing'
Utterance: 'I definitely need firewood as well. We didn't anticipate it being as freezing cold as it is at night. There isn't much around us. We've also been using a lot of water, which we could use more of since we've been looking for firewood.'

Yes
