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.

[Q]: Context: 'It was going great until a bear came and took all of our food 😮' 'Oh no, that's not good.  I still have some left over, but we're running out of firewood to use to heat it.' 'Seems like we are in the same boat, the bear tore our tent to shreds so we are sleeping outside and it is cold☹️'
Utterance: 'Sounds like a rough camping trip.  It has been pretty cold lately.'

[A]: No


[Q]: Context: 'so I would have 2 water, 2 food and 1 firewood? My kids were looking forward to making s'mores. If I could get 2 water, 2 firewood and one food, that would be great!' 'You would get 2 water and 2 food, I would get 1 water and 1 food for hiking and 3 firewood for having to stay out longer in the dark to complete my hiking goals.' 'doesn't really seem fair for you to get all the firewood. I would like to have at least one because then we're completely in the dark.'
Utterance: 'You get lots of water and food for your children, I am cutting back on my goals by giving up energy which means I have spend more time outside hiking.  I do need to stay warm'
