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.

Example Input: Context: 'Thank you for the two firewoods. I totally understand that. Since we do have young children I want to make sure they stay hydrated so I would be willing to give you two if I can just have on extra for them.' 'OK. Your children must be hungry, could we give them two food while we keep one?' 'That would be wonderful. Okay so I'll take two Firewoods, two food, and one water. Does that work?'
Utterance: 'Almost. I actually had a disagreement with one of my friends just now because he is a bigger guy, haha! 🙂 Could we keep one of those foods for him? I'll give you another firewood for it.'
Example Output: Yes

Example Input: Context: 'I do too.' 'Can you give me your offer?' 'I would like 3 firewods 1 food and 1 water we stay up late and need extra firewood'
Utterance: 'Oh thats expensive .There's too much cold out here and thats our major package for survival '
Example Output: Yes

Example Input: Context: 'I can give out the food in exchange for the firewood' 'Okay. I need all of the water, if you're getting the firewood. ' 'I can't give out all the water. I need to be hydrated as well. '
Utterance: 'You already have all the basics, though, so you won't lack sufficient water to be hydrated. I have a serious medical condition that requires that I have access to additional water. '
Example Output:
No
