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: 'My friend ended up having a medical emergency and couldn't go to the store when I asked her to get food. Because of that, I would like 3 food packages. I had to go help her with the medical forms and didn't have time to shop' 'Yes I can give you the three food but I need 2 water. I can become very thirsty. ' 'Yes that is totally fine with me. What about firewood'
Utterance: 'I can give you 1 of the firewood. I would like to stay warm at night so I want 2. 😮'

SOLUTION: Yes

PROBLEM: Context: 'Sounds good I will give you the 2 packages of food.🙂' 'So nice of you !!  Now can you summarize your needs?' 'I will need 3 packages of firewood. 1 package of food and 1 package of water. What are your needs?'
Utterance: 'Yes, you are absolutely right. Thank you very much !! I'll take 2 package of food and 2 package of water .'

SOLUTION: No

PROBLEM: Context: 'Food is the most important to me because I need to eat more often so that I can take my medications.  ' 'Yeah, that is important. I do not have a problem letting you have more food than me.' 'Would it be possible to get an extra water also?  How do you feel about the firewood?  I wish we could split everything evenly.🙂'
Utterance: 'Me too. Firewood is the most important thing to me. We will be somewhere cold and we could use the extra warmth.'
