Detailed Instructions: 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.
See one example below:
Problem: Context: 'That sounds pretty reasonable as I am in need of firewood the most. Would it be most reasonable to each take what we need most and split the water down the middle?' 'Yes, it would.' 'I think that sounds fair. The problem is that there are 3 waters and one of us would get two and the other one. How should we sort that?'
Utterance: 'You can take the two water. I am not that thirsty most days.'
Solution: No
Explanation: In this utterance, the participant does not use self-need since they do not talk about any need for themselves.

Problem: Context: 'Oh.  That sounds fun.  I'm getting ready to go camping with my family next weekend as well.  It will be the first time that my kids have gone camping with me.' 'Aw that will be a great time then 🙂 How old are your kids? ' 'My kids are 14 and 12.  So they're fairly independent - but I also know that they want to do a lot of cooking during our camping trip.  Thus, I think that I'm going to need more firewood as I expect that we'll be having a lot of fires while we're out.  How about you?  What are you planning to do on your camping trip?'
Utterance: 'Good ages. They should be able to help out. We're planning to do a big bonfire, maybe some smores, and hopefully find a lake. We're looking for extra firewood and water for the bonfire and to keep hydrated'
Solution:
Yes
