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 Input:
Context: 'Firewood is definitely important as well! Last time I went camping we ran out pretty fast, so I want to be extra prepared. 🙂' 'Oh no! I can see why that would be extra important to you! I will give you two of the firewood for two of the water' 'That sounds good to me! I think since water is pretty important on a camping trip (especially with a baby!), and since you are getting 2 extra packages of water, may I ask that I get 2 of the food packages? I have 2 (always hungry) preschoolers joining us haha! 🙂 I can never seem to keep them full'
Utterance: 'I wish there was a way to split that third package of food in half because I am so worried for my husband's diabetes, he constantly needs food as well ☹️'

Ex Output:
Yes

Ex Input:
Context: 'Yes the cold is hard to adjust to I can't seem to shake the chill.' 'I could really use some extra firewood!' 'So could I. How about we split the firewood?'
Utterance: 'How about I take 2 firewood but you can have 2 waters? Water is pretty important and I have a little extra.'

Ex Output:
No

Ex Input:
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.'

Ex Output:
No
