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: 'Since I have never been camping before, why do you think you need 2 firewood?' 'Unfortunately, I have arthritis so being sure to keep warm and the dampness away in the evening, heat is important for me.' 'Ok.  I am worried about animals and bugs so I would prefer 2 firewood.  But I am happy with the 3 food🙂'
Utterance: 'Ok, how about we shift a bit as I hear you on the bugs and animals.  I think I can get by with one firewood and use extra covers and meds.  But, will need plenty of water and some food.  How about I take 1 firewood, 2 water and 2 food.'
[A]: No


[Q]: Context: 'Well hopefully it will be cooler up in the mountains. What supplies are you in need of?' 'I am a big eater. I tend to eat a lot throughout the day. You? 🙂' 'Ha I get that! I'll need that too, but mostly water because my family wants to do a lot of hikes.'
Utterance: 'Thirty I see. No problem, we'll work something out. 🙂'
[A]: No


[Q]: Context: 'Looking forward to this camping trip!  I am hoping we can find something amicable with these additional resources.' 'I'm excited too 🙂. Things have been stressful lately. What are some things that you value most?'
Utterance: 'It's supposed to be chilly where we are heading and I could really use some extra firewood.  🙂  What about you?'
[A]:
Yes
