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.

Context: 'That does not seem entirely fare but I need more water so I will take this deal' 'It's honestly not that fair to me either, but sometimes we just end up with slightly conflicting priorities in life.  🙂  I think making the best of the situation is the way forward.' 'Yeah, That's true,🙂, so do we have a deal?'
Utterance: 'Yup, the food to me, the water to you, and 2 of the firewood to me, 1 to you is as I understand it!'
No

Context: 'Hi! I'm very excited for the upcoming camping trip!! 🙂' 'Me too! 🙂 What do you think about the extra supplies?' 'I recently bought two new puppies, and they are coming on the trip. I could really use the extra water for them!'
Utterance: 'Awww. That sounds reasonable to me. I'm hoping to have a birthday dinner for my dad on the trip, so I'd appreciate some more food and a little more firewood.'
Yes

Context: 'I am fine with the cold although I might need some to set up the fire. I have a baby with me so I might need to heat up the milk or food. ' 'Oh, I see. How about 2 firewood for you and 2 food. I keep the rest' 'I don't really need food. I can do it with 1 firewood so you can get the rest. But I really need water. We are going hiking and drink a lot.'
Utterance: 'Ok, would you do 1 firewood, 2 water and 1 food then?'

No
