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: 'not soo good, i am hungry' 'Uh oh. What are you preferences on supplies?' 'food, then water, then firewood, and yours?'
Utterance: 'water, food then firewood. It's really hot so I need to make sure we are hydrated. We forgot a bag of supplies that had mostly food so we really could use food. It's hot so firewood isn't necessary. If anything we can get it from around or on a hike.'
[A]: Yes


[Q]: Context: 'I would do this instead: 3 firewood, 1 water and 2 food.' 'That's not going to be a fair offer, you'll need to do better than that or I don't think we can come to an agreement' '3 firewood, 1 water, 0 food'
Utterance: 'so I'll get 2 water, 3 food and 0 firewood?'
[A]: No


[Q]: Context: 'O cool🙂. I can give you all the water and we can split the fire wood. I need a least one firewood to make a fire for my son' 'I can give you one firewood if you can spare one food for me to eat while I am cooking.🙂' 'Ok if I can keep one water as well 🙂'
Utterance: 'I may not be able to go without the water. I am making a large pot of soup with homemade bread.'
[A]:
Yes
