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: 'Fine.' 'You aren't very talkative are you? What preferences do you have for packages?😮😮😮' 'I would really like 2 water and 2 firewood and 1 food.'
Utterance: 'I would like 3 water no firewood and 2 food. I have 8 people in my family and I have a medical condition where I can only drink water and have to drink 100 ounces per day.'

SOLUTION: Yes

PROBLEM: Context: 'Yeah, sorry, that's not going to work out for me.  I'm going to need at least 2 bottles of water, 1 food packet, and one firewood.. again, this does leave you with two each on the food and the firewood, which are both very important things for this camping trip!' 'but thats the only offer im willing to give' 'Well then unfortunately I think we're gonna have to walk away from this and neither of us gets anything we could both use.. that's unfortunate and I'm sorry to see it end in such a less than magnanimous fashion ☹️'
Utterance: 'you need water and i need food so unless we do 1 food  to 1water is tht okay'

SOLUTION: No

PROBLEM: Context: 'I was thinking firewood, because the most fun I have camping is roasting marshmellows and hanging out around there. How about you?' 'Oh hmm. I really need extra firewood because I forgot to bring a sleeping bag. I will be freezing to death at night. ☹️' 'Okay, well tell me what you need the least of, if you don't mind.'
Utterance: 'You can have all of the water if you let me have all of the firewood.'

SOLUTION:
No
