Detailed 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.
Q: Context: 'You really did have a good day didn't you! Sounds like fun. How many fish can one person eat? If I don't have the extra firewood I'm going to be really cold tonight. ☹️' 'I am here with my family and we love to eat fish.🙂  Maybe if you spend tonight sleeping in your car or camper I can keep the fire wood. In exchange I will give you the 2 additional food packages and all 3 of the water packages. It's only for 1 night.' 'Why would you want to give up all that water? You're going to need extra water for your family to drink. All the sodium in the fish is going to make you all thirsty!'
Utterance: 'Your right,😮  I didn't think about that. But will probably only need 1 extra package of water so, in exchange I will offer you 1 package of firewood.'
