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: 'I am so excited to go camping!  I am planning a nice long walk in the woods to decompress from the hectic days of working.' 'I am too.  I've been thinking of this since COVID.  I hear we have some materials to share between the two of us.  What are you thinking?  For me, I am from the South so I get cold easily 🙂 so firewood is my main priority.' 'Perfect!  I'm a northerner, so the firewood is all yours!  I'll need lot's of water to keep hydrated after the hike, and I'll probably be pretty hungry too.'
Utterance: 'My spouse calls me a water buffalo so I'm pretty water dependent if you couldn't tell.  '

A: Yes
