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.

I was wondering if we could start with the water? any chance i could have it all and you can have all of something else? thoughts? im open to discussion' 'I am actually very much in need of water. I fell while I was hiking during this trip. I have a really bad wound I need to clean on my leg.
