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.

Utterance: 'Okay that works well. I accept! 🙂'

Ex Output:
No

I also am low on Food and would need at least 2.' 'That doesn't sound like something I can agree to. Do you have any other ideas?'
Utterance: 'I can keep 2 of the firewood then and offer you 2 of the food. I'd take the water, 2 firewood and 1 water'
