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: 'Hello' 'Hi there.. how are you doing today?  I hope well!  🙂  So, it looks like we need to divy up these supplies, huh?  Do you have any thoughts on the issue?' 'I'm doing fine thank you, how about you? Well for my trip I'm most interesting in socializing so a great campfire a night would be great, I'd prefer not to boil water either so want extra of that too. Food less so as I will go fishing and know wild vegetables, fruits and mushrooms I can pick. How about you?'
Utterance: 'Awesome.. it seems like we're kind of on the same page here then as I'm going to need food for my people since they're not real self-sufficient but I'm less neurotic about the water or the firewood.. we're from Florida so we actually kind of like the cooler weather anyway.. lol'
[A]: Yes


[Q]: Context: 'Hello. I really just need firewood for my wife and daughter and some extra water for myself.' 'Hello, i also need firewood, i have a medical condition where it is very hard to maintain my body temperature. ' 'My wife is in the same boat. That sucks. I wonder if it will be cold.'
Utterance: 'Well i do not need the water at all as i have a distiller'
[A]: No


[Q]: Context: 'Water was my high priority and food was your's, so I think we already split the difference there. ' 'Okay, so how do you propose splitting the firewood?' 'Can we split a bundle, in the real world that would be cool.  '
Utterance: 'I wish we could. I would be down for that. 🙂 That seems the most fair to me. How about you enter the trade deal on your end?'
[A]:
No
