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: 'I would really like to have 3 waters and 3 firewood because this is my first time camping and I don't have survival skills. ' 'You must be a comedian. We will need to come to a compromise because there's no way that's going to happen. I am like a water buffalo so I'll need at least two waters. In addition, my family is from the South and will need firewood as well.'
Utterance: 'I can't swim too. I think two waters will help me to survive on this trip and I will need at least two firewood to make fish or other food items for my family. '

SOLUTION: Yes

PROBLEM: Context: 'Hello!' 'Hello, how are you doing today?' 'i am doing great! how about you?'

PROBLEM: Context: 'Hi friend. 🙂 I'm going camping in the woods near my grandparents cabin. I'm inviting some friends along for a little bit of fun too because they have a guest house and a great field for tents. Would you like to come too? ' 'Oh that sounds awesome. I am actually going camping with my grandparents and my children. So I would love to have 2 firewoods for them. They get cold easily so I would like a little extra to make sure they can stay warm throughout the evening. 🙂'
Utterance: 'Yes, I would love to give you two firewoods! 🙂 My grandparents might check in on us, they like camping. But my grandpa has rheumatic problems so he needs lots of water. Could we take all three?'

SOLUTION:
Yes
