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: 'I apologize but that will not work. I have a diabetic and need to make sure they will have enough food for a hike. So I would like to take two food packages, one water, and two firewood. ' 'That won't work. Because, we are planning for a campfire. And so, we are in need of fire wood. I hope you understand.🙂🙂🙂' 'I understand. We are also planning a campfire, and have a lot of young kids who will need the fire to stay warm. So that's why I feel I need two firewoods. 🙂'
Utterance: 'Sorry for apologize. Here we are having old aged people here. I need two packages of food. Otherwise two of firewood.🙂'

Ex Output:
Yes


Ex Input:
Context: 'Hello! We're going camping and need some additional supplies. The primary need right now is firewood! We can spare water, but some additional food for the six kids is needed!' 'Wow. You took six kids on this trip? I would say you will definitely need food!'
Utterance: 'Yup! But we did think ahead and ordered extra rations for them. Food is second priority, so maybe we could have 2 of those? You could have all of the water rations.'

Ex Output:
Yes


Ex Input:
Context: 'Ok, what item do you need the most and which item do you need the least? That information would help me think of an offer that suits both of us.🙂' 'I need   food and water the most . There are 3 of us.🙂' 'Your most needed item is water or food?'
Utterance: 'Most needed is both food and water. I guess food is my highest priority .🙂'
