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.

No

Context: 'I will  be happy to let you have 3 packs of food , but I need 2 packs of firewood' 'I am also letting you have all 3 packs of water. I think we need to consider how to split the firewood in a fair manner.' 'What do you think is  a fair deal with the firewood'
Utterance: 'The person who needs it the most should get 2. I think I need it more because I didn't bring a warm sleeping bag.'
