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: 'Sorry, I sent my last message inadvertently. I meant to say that that sounds great! Yes, I can understand the need for extra water for the hike. With the size of my family, I could use a bit of extra food for our trip.' 'We can get by with less food since the girls will be looking to forage in the forest to get a badge.' 'That's awesome! Since we have the basics, would you be willing to swap 3 packages of food for 3 packages of water?'
Utterance: 'We will need two food so we can fill their bellies, but I will be glad to offer you all the firewood since I can use my axe and get wood for us.'
Output:
Yes
