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.

[EX Q]: Context: 'Hi there! How are you?' 'Great! I'm very excited to go camping, how about you?' 'I am! Now, I need a lot of firewood because we were planning on burning some earlier (to start cooking meals and such). I also need some extra food in case bugs come and eat some (like last trip, ugh). How about I take 2 firewood, 2 food, and you take 3 water, 1 firewood, and 1 food?'
