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: 'HI how are you today?' 'Good. I am diabetic so would like to take 3 of the food' 'I would do that but our meat spoiled because the ice box was not properly closed. How about you get 2 of the meat, and I get 3 of the water?'
Utterance: 'ok I will just be able to get by with 2 of the food, I can give you all 3 of the water if I can take 2 of the wood. I have panic attacks in the dark.'
