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.

Context: 'I am' 'Me too! Is this your first time?' 'I have been camping before, but it has been a while. You?'
Utterance: 'Same for me!!'
No

Context: 'I need a lot of food today. I was advised to eat at least 4 times a day so i may need all the food packages.' 'Well that is not going to work well for my family of 8 now is it? Haha. I think we can come to some sort of agreement though.🙂' 'What do you propose?'
Utterance: 'I really need food too, but I am willing to deal and let my kids go hungry I guess ☹️ I propose I get one food, 3 firewood and 1 water.  '
Yes

Context: 'That sounds like a blast.   I would like to propose that you take 2 waters and 1 firewood and I'll take 2 firewoods and 1 water for our respective trips.  Does that work for you?' 'Yes, we are all looking forward to it. Thanks for being amenable and trying to make this work. That might be okay, but could we take take the 3 packages of food? Since we won't be doing as big of a bonfire, I am sure we'll hike more or swim and need the extra energy' 'I was hoping to take at least some of the food with me.  As you know, those teenagers seem to hungry ALL the time.  It's like feeding fuel into a bottomless pit.  So I'm definitely going to need some of the food for my trip as well.'
Utterance: 'Hm okay. Would 1 packet of food be sufficient? I know they are growing but my friends are ex football players and can eat 3x the normal person'

Yes
