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: 'I was going to say, the fire would be probably one of the few things I would be interested in! I love being warm.' 'Well you can take all the firewood if it will help, would it be ok if i get all the food in return?' 'That works for me. How would you like to divide the water?'
Utterance: 'I am ok with you taking two waters since you are new to camping, does that seem fair to you?'
No
