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: 'All my girls have brought canteens. I must have enough firewood if they will earn their badge. You can have one, but I won't be able to make due without 2.' 'I could manage with one firewood and two foods, but if you have canteens for everyone, may I then have all three waters? I had planned to collect water from the river, but I'm worried I may get sick.' 'you pointed out that we will need more!  😮 i will take 2 waters'
Utterance: 'I didn't know you had supplied everyone with water before the trip. I was merely trying to look out for your needs, but you said you didn't need them!'

SOLUTION: No

PROBLEM: Context: 'Good how are you' 'I am doing quite good. I enjoy camping. I however did not bring enough food.' 'Ok I'm sure we can work it out because I know I need extra water and firewood. Do you have any ideas on how to divvy up the extra supplies?'
Utterance: 'I would need some firewood as well, as I need it to cook the food. I was thinking maybe you can have all the water and I have all the food.'

SOLUTION: Yes

PROBLEM: Context: 'Water is a little important to us too though , if possible maybe we can split that or maybe we can get some more food in replacement.' 'That may be possible.... 🙂 What did you have in mind for the food replacement? ' 'You can have all the water if we can have all the food?'
Utterance: 'I dont think I am okay with that ☹️. Food is essential to our groups morale when camping. We would like 1 additional food preferably.'

SOLUTION:
Yes
