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: 'I am doing quite good. I enjoy camping. I however did not bring enough food.' 'Ok I'm sure we can work it out because I know I need extra water and firewood. Do you have any ideas on how to divvy up the extra supplies?' 'I would need some firewood as well, as I need it to cook the food. I was thinking maybe you can have all the water and I have all the food.'
Utterance: 'All the food is too much, I would need at least one package of the food for my group. I was thinking you could have 2 of the food packages and I have 1, then I get all the water and the majority of the firewood. That leaves you with 2 of the high priority food packages and a package of firewood to cook the food.'
[A]: Yes


[Q]: Context: 'In that case, I would be fine trading the extra food for a water. so you would get 2 waters and 2 foods ' 'Hmm, that works for me. So basically, you get 1 food, 1 water, and 2 firewood? I get 2, 2, and 0. If that's right, I agree.' 'Yea, so that about right, but i get 3 firewoods'
Utterance: 'Oh, yeah, sorry, mistyped that. Okay, let's do it then. Was good talking.'
[A]:
No
