Instructions: 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.
Input: Context: 'It's going well.  🙂  How is yours?' '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.'
Utterance: 'Seems like we are in the same boat, the bear tore our tent to shreds so we are sleeping outside and it is cold☹️'
Output:
Yes
