TASK DEFINITION: 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.
PROBLEM: Context: 'ok I will just be able to get by with 2 of the food, I can give you all 3 of the water if I can take 2 of the wood. I have panic attacks in the dark.' 'Okay that works for me as well.' 'awesome any chance I could persuade you to substitute your 1 food item for an additional fire wood 🙂'
Utterance: 'No I cannot do that unfortunately. We brought just enough food for our weekend trip, and I cannot lose any or we will run out before our camping trip is over.'

SOLUTION: Yes

PROBLEM: Context: 'I was just negotiating the water for now.  I was trying to do one at a time.' 'ah, I'm definitely ok with doing one at a time: A 2:1 split is definitely OK with me: The issue is, if we consider each individually, it might be harder to come to a deal, but I'm happy to do it your way.' 'How about you take 1 firewood, I''l take 2 and with food, you can have 2 and I'll take one package.  I have two very hungry boys!'
Utterance: 'Is there a reason you want the 2:1 split? Food my group's largest priority by a large margin (We eat a lot). It's worth a lot more to my group then the firewood would be.'

SOLUTION: Yes

PROBLEM: Context: 'Hi! I'm super excited to camping with my family! We have had to cancel all our original travel plans due to Covid and we're really looking forward to this trip. Especially my son! He's been so restless at home. Are you going camping too?'
Utterance: 'Yes, I am! I can't wait. I'm going on a 3 week trip to this gorgeous lake.'

SOLUTION:
No
