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.

Ex Input:
Context: 'yeah you are right, but water is essential for all !☹️, you must consider that too' 'I agree water is needed. I can do 2 water 2 firewood and 0 food' 'you consider me giving one of your water package and collect food package, if you are lucky you can get liquid foods too🙂'
