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.
Q: Context: 'So if we were to split the firewood more in your favor and I were to take all the food, and then we kind of split the water, I think we could maybe make a deal here?  🙂' 'I think that is definitely doable! I'd be glad to make a deal with you. Thanks for being so reasonable! 🙂🙂' 'So I'm proposing 1 firewood to me, 2 to you.  3 food to me.  And 2 water to me, 1 to you.  Can we work with that?  Firewood seems to be important to the both of us so I'm giving up things here.'
Utterance: 'Yes I think that will work just fine. Firewood is important especially because I usually find my food in the woods.'
A: 
Yes
