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: 'Nice, are there any extra supplies that you will really need?' 'At the camping site. Yes, I would like some water and food to refill the used packs' 'I was hoping to get alot of water as well, would you be ok with me getting two waters and three firewoods if you get all the food and one water?'
Utterance: 'Hmm, that's not favorable for me going by the volume of items left in my arsenal. Water is more of a higher priority than food. So, I would exchange 1 pack of food for an additional water'
Output:
No
