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 could make that work 🙂 I'm sorry if I came off mean, I'm just trying to make sure I'll be ok. I don't camp often, so I'm not sure how to prepare.' 'I understand. What are you using the extra food for?' 'I brought some pre-packed snacks, and a few sandwiches. I'm hoping there are no hungry animals around. What about you?'
Utterance: 'I was hoping to get some extra food for some picky eaters, but if they are hungry they will eat!'

SOLUTION: Yes

PROBLEM: Context: 'They sort of need more water for their meds' 'I'm sorry to hear that! But can you spare 1 for me since you probably don't need all the water.' 'Sure that sounds fair. Thank you. Besides water what do you need for your trip?'
Utterance: 'great. Then can you give 2 food instead? We eat a lot and need more to go through the night...'

SOLUTION: Yes

PROBLEM: 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.'

SOLUTION:
Yes
