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: 'Can I get 3 packages of food?' 'What do you need it for?' 'I would like some extra food in case I get hungry.'
Utterance: 'Okay that sounds ok, I can do without the food. I also need two packages of water because it will be very hot out.'
[A]: No


[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: 'I am okay. How about I give you one and half then I get some firewood from you?' 'No I need at least 2 waters.  But I am willing to give you all 3 foods, if I get all the firewood.  Does that work for you?' 'Okay I will give you 2 waters. I actually need more of firewood. If I can get 2 I will be glad.'
Utterance: 'Well I really need the firewood because I have small kids with me and it would be hard for me to get some free time to get the firewood, but I would be willing to give you 2 firewood since I get two waters.  What are your thoughts about the food?'
[A]:
Yes
