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.

'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.'
No

Context: 'I can also understand your family situation. I'll give 1 package of water.🙂' 'That works for me.🙂 Are you able to share the food if I give you 1 firewood?'

Utterance: 'Sounds good I will give you the 2 packages of food.🙂'
No
