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.
Input: Context: 'I really appreciate that. Do you think you will be okay with just 1 water since you have health issues?' 'That would be very nice, but I worry about you not having enough on the trail.  Dehydration would not be good.  I am pretty sure I can ration my supply to make it last.  🙂' 'You're a good friend! I'm excited to embark on this adventure! 🙂🙂🙂'
Utterance: 'Me too!  So let me clarify:  I will take 2 firewood, 1 water and 1 food.  You will take 1 Firewood, 2 water and 2 food.  Is that right.  🙂🙂🙂'
Output:
No
