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.

[EX Q]: Context: 'Hmm. Maybe we could go out together on a run. 🙂Always nice to have a running partner. So maybe on the water you get 2, me 1. Then on the Firewood the opposite?' 'That would be fun! I feel like I always do better when I have someone to run against.  Competition does me good. That sounds fantastic on the fire wood and water split.  What is your food situation looking like??' 'How about this? 2 for you and 1 for me. Going low carb and mostly brought my own. What do you think? '
Utterance: 'That sounds great! I don't think my chances for catching any fish are pretty slim!'
[EX A]: No

[EX Q]: Context: 'one of my kids is on medication so we are going to need to pack a lot of water. so if could spare that it would be appreciated.' 'Well sadly I plan to go hiking a lot so I will need lots of water, but perhaps we can come to a reasonable agreement if I have to shorten my hikes.' 'ok what do you have in mind?'
Utterance: 'Well if I gave you a majority of the water, I would like 1 water, 3 firewood and 1 food.'
[EX A]: No

[EX Q]: Context: 'Can you help out? I can easily dehydrated can you give all the water packages to me?' 'I can spare a little as I am currently taking medication that requires me to drink a lot. I can give you 2 bottles of water if you can give me 3 firewood' 'I can't give you all the 3 firewood. We can share them. I can give you 1 firewood? Because I am too scared about dark. ☹️'
Utterance: 'I could give you 1 water for 1 firewood, most of my firewood got wet so is almost useless . Would you perhaps except some food for another unit of firewood?'
[EX A]:
No
