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: 'Hi I am also going camping. Unfortunately I need as much firewood and water as possible too. I need to be able to cook our food and stay warm all night ' 'Can I ask how many people are camping with you? Are you planning on hiking the mountain?' 'Oh yes, I have my whole family coming. I'm really excited because we don't see each other often. My aunts, uncles, cousins. Some of us will hike while others stay back. Maybe we can come to an agreement? Will you also be hiking?'
Utterance: 'Yes hiking for sure.  If I take 2 firewoods and give you 2 waters and 1 food, would that be acceptable?'

SOLUTION: No

PROBLEM: Context: 'Hi I would like to trade you food for some water 🙂' 'How many food would you like to trade for water?' 'How about 2 Water for 3 food?'
Utterance: 'That sounds like a good deal but I could use some firewood as well. Would you throw one of those in as well?'

SOLUTION: Yes

PROBLEM: Context: 'I am actually planning to make a big dinner for the whole camp tonight. I will feed everyone if you can let me have the water and firewood. You can take the food to eat before dinner.' 'O cool🙂. I can give you all the water and we can split the fire wood. I need a least one firewood to make a fire for my son' 'I can give you one firewood if you can spare one food for me to eat while I am cooking.🙂'
Utterance: 'Ok if I can keep one water as well 🙂'

SOLUTION:
No
