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.

Context: 'O cool🙂. I can give you all the water and we can split the fire wood. I need a least one firewood to make a fire for my son' 'I can give you one firewood if you can spare one food for me to eat while I am cooking.🙂' 'Ok if I can keep one water as well 🙂'
Utterance: 'I may not be able to go without the water. I am making a large pot of soup with homemade bread.'
Yes
