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: 'We both sound pretty reasonable! So you think you need 2 firewood?' 'yes please,  i  dont require much food or water 🙂' '🙂  You're being very accommodating! So right now I have 2 food, 2 water and 1 firewood. And you have 1 food, 1 water and 2 firewood, right?'
Utterance: 'that sounds good to me, if you want to give me another food i would take it but ok if not '
No
