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: 'Great thank you. I am looking for primarily some firewood and food for my camping trip soon. ' 'I'm going camping too and also need food and wood, mostly food though' 'Okay I understand that! Is there a particular reason that you do not need much water?'
Utterance: 'I figure I could always get some at the stream 🙂'

Ex Output:
No

No
