Definition: 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.
Input: Context: 'I know how to filter water so you can have all of the water. I would like as much firewood as possible.' 'me too. I don't care about water since we are camping near a river.' 'I would consider giving you all food and water if I could get all of the wood.'
Utterance: 'Oh really? I think I am able to do it without firewood then. The kids will be full and probably won't ask for smores'
Output:
No
