Q: 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: 'I need 2 packages of both food and water on each' 'Food is a hard one to give 2 packes of since I dont have very much and need to feed my family. We do have plenty of water though. Would you be willing to take 3 packages of water and only get 1 package of food?' 'Is any other item is left with you to add '
Utterance: 'I would be willing to give you 3 water, 1 food, and 1 firewood which we be 5 packages for you. I would take 2 food and 2 firewood which would be 4 packages for me'
