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 self-need strategy, otherwise output No. self-need is a selfish negotiation strategy. It is used to create a personal need for an item in the negotiation, such as by pointing out that the participant sweats a lot to show preference towards water packages.
PROBLEM: Context: 'That's fair, but I have wiggle room on the water, how about I take two food, two firewood and you take 3 water, 1 food, 1 firewood?' 'Is there anyway you will go with that I get two firewood? I need food the most but since you get most of that can I get most of the firewood? So 1 food, 2 firewood, and 2 water for me?' 'You drive a hard bargain. I could really use that firewood. It's going to get cold tonight and these sleeping bags are not worth the price I paid ;)'
Utterance: 'Haha, I know but I am in the same situation! ☹️ and since I am getting less food I feel like it is fair I get on more firewood since I truly need that 🙂'

SOLUTION: No

PROBLEM: Context: 'He definitely does drink a lot of water, but he's in a growth spurt so 2 would be ideal. I'm happy to give up all firewood in exchange for the extra food!' 'okay that sounds like a better deal then! I will take all the firewood and 1 food, and you can take the 2 food packages' 'Awesome, I appreciate that. How does the water need look on your side?'
Utterance: 'I think having two waters would be good for me because my mom forget to pick extras up at the store yesterday😮'

SOLUTION: Yes

PROBLEM: Context: 'That sounds amazing and delicious! maybe we can compromise? Maybe, I can get all 3 waters and you can have all 3 Foods? what do you think? ' ' I would agree to that if I can also have two things of firewood. I am going to need a lot of wood, so I can cook the meals I am making 🙂' 'I completely understand, thank you for compromising with water and food. Wished we had 4 firewoods to divide and share it equaly, may I ask how long will you be camping for? Im afraid I need 2 firewoods as well, maybe we can see who has the greater need? '
Utterance: 'I am going to be camping for a couple of weeks, so I will need quite a bit. I also realized some additional water would be good, because I have some meals that need me to boil water. Maybe you can have 2 firewood in exchange for me having one of your waters? Then you would still have plenty of water, but also plenty of firewood 🙂'

SOLUTION:
Yes
