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! 🙂' 'I hello I need firewood to survive'
Utterance: 'oh my are you going somewhere cold? I could use the water, I am going on a charity event with kids from the Make A Wish foundation. Its going to be their first time!'

[Q]: Context: 'i botttle of water for a can of food and 2 firewoods' 'Yeah, sorry, that's not going to work out for me. I'm going to need at least 2 bottles of water, 1 food packet, and one firewood.. again, this does leave you with two each on the food and the firewood, which are both very important things for this camping trip!' 'but thats the only offer im willing to give'
Utterance: 'Well then unfortunately I think we're gonna have to walk away from this and neither of us gets anything we could both use.. that's unfortunate and I'm sorry to see it end in such a less than magnanimous fashion ☹️'
[A]: No

[Q]: Context: 'How about if I give you 3 food for 3 waters, and then we split the firewood?' 'I do require at least one water, hiking is very physical demanding. Also there are 3 firewoods?' 'yes there are 3 firewoods. Okay I understand about the water. then how about 2 foods for 2 waters, and we somehow divide the three firewoods? 🙂'
Utterance: 'Could I possibly get 2 firewoods? Assuming Water is your high value item?'
[A]:
No
