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: 'Hi! How are you?' 'I am fine. How is your camping trip going?' 'I'm just finishing the final details of packing. I'm a little concerned I don't have enough of a few things. It is supposed to be over 100 degrees where we are going, and I don't think I have enough water. I'm concerned my kids are going to get dehydrated. I really could use 3 extra packages. '
Utterance: 'That will not be possible i am afraid. I need at least 2 packages of water too. I have some tabs that i have to take with water regularly.'
Output:
Yes
