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: 'Sorry, that can't work for me. Is there a reason you need all the firewood and food?' 'I have health issues, and I need to keep warm at night.  And I don't know how much fish I can catch.' 'Okay, that makes sense. But I also need to keep warm.'
Utterance: 'I think I can get by with 2 firewood, and give you 1.'
[A]: No


[Q]: Context: 'Yeah, I'm going to the desert so I'm hoping to have enough water. I'm good on food and I hunt for a lot of it anyways.' 'I've never been a good hunter. I wish I had those abilities.' 'I would part with all the food if I could get all the firewood.'
Utterance: 'That seems fair. How about water. How would that be split? I'm very concerned.'
[A]: No


[Q]: Context: 'Hello, how are you?' 'Hello, I am doing well, I am excited about my upcoming camping trip, how are you ?' 'I good thank you.  Yes, I am excited about this trip but I have been worrying about how I can get more firewood.  A raccoon came and stole mine this morning from the campsite.  So would it be alright if I kept all 3 firewoods?'
Utterance: 'No, I have all of my children here with me, they are all afraid of the dark so must burn the fire all night, as I brought no additional source of lighting.'
[A]:
Yes
