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: 'Hello, I'd like to get all of the water, an extra firewood and 2 of the food'
Utterance: 'Hi there.  That hardly leaves me with anything and doesn't really work for me.  I was hoping to make a campsite feast and get the extra food.  If we can do that, I'd be happy to give you all the water and that extra firewood.'
Yes
