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: 
Utterance: 'Hi, I would like to get 2 additional packages of food, 2 additional jugs of water, and 1 additional bundle of firewood. I need the additional food because I will have 3 children with me on the trip and one of those being a baby. The baby needs water for her bottles and I need an additional bundle of firewood to warm her bottles.'
[EX A]: Yes

[EX Q]: 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 A]: Yes

[EX Q]: Context: 'That will not be possible i am afraid. I need at least 2 packages of water too. I have some tabs that i have to take with water regularly.' 'I don't think I will be able to give you 2 waters. I'm desperate. I need at least 2. I would give you 1 if I could get 3 packages of food. I would give you all the firewood. ' 'If i give you 3 packages of food then i will take 3 packages of firewood.'
Utterance: 'So I get 2 waters and 3 foods. and you get the rest?'
[EX A]:
No
