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.

Ex Input:
Context: 'Hello! I'm packing for my camping adventure.' 'I am too.  I am so looking forward to this.  ' 'Yes! I am so on the same page as you. I want to be sure I'm set and prepared. 🙂'
Utterance: 'Would you consider letting me have 2 of the 3 extra firewood?  I have health issues and I get really cold sometimes.☹️'

Ex Output:
Yes


Ex Input:
Context: 
Utterance: 'Hello there, I'm in a lot of need for some firewood! I'd not be against taking most of it if that's alright?'

Ex Output:
Yes


Ex Input:
Context: 'That would be great! I don't need food as much as I am in need of firewood, to be honest.' 'I brought purification tablets so I can make do with rainwater or river water.  How about you?' 'That's very smart! 🙂 Way to be prepared! I didn't think to do that.'
Utterance: 'So if we were to split the firewood more in your favor and I were to take all the food, and then we kind of split the water, I think we could maybe make a deal here?  🙂'

Ex Output:

No
