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: 'IF I can't get 2 pieces of firewood, I will walk away' 'oh that is too bad. I feel the same way.😮' 'Sorry we could not come to a agreement, I am walking away'
Utterance: 'OK. I am sorry it has to come to this. I really need the firewood as much as you do to keep warm as it is very cold where I am for this time of the year.'

SOLUTION: No

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

PROBLEM: Context: 'I good thank you.  Yes, I am excited about this trip but I have been worrying about how I can get more firewood.  A raccoon came and stole mine this morning from the campsite.  So would it be alright if I kept all 3 firewoods?' 'No, I have all of my children here with me, they are all afraid of the dark so must burn the fire all night, as I brought no additional source of lighting.' 'ok, fair enough.  How about I take 2 firewood as 1 should do you for a couple nights. I also have small children with me and would like to have the fire burning at all times to keep the bugs away. '
Utterance: 'I really dont see giving up that much of the wood as I cannot risk running out myself. We are camping way too far out to get access to additonal lighting. I tell you what if you will let me have 2 of the fire wood I would be willing to give you two of the food items. I know that racoon probably took your food as well!!'

SOLUTION:
Yes
