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.

Q: Context: 'I really need some more food. I only have the basics, and I'm afraid it's not going to be enough. What about yourself?'

The firewood I dont need to much off and I need very little food as I am dieting. lol 🙂' 'I totally understand that. And it's pretty important, lol '
Utterance: 'It sure is..So how much food do you need for the trip? Do you need firewood to cook the food? Thank you for understanding my issues. 🙂'

Q: Context: 'I was just negotiating the water for now.  I was trying to do one at a time.' 'ah, I'm definitely ok with doing one at a time: A 2:1 split is definitely OK with me: The issue is, if we consider each individually, it might be harder to come to a deal, but I'm happy to do it your way.' 'How about you take 1 firewood, I''l take 2 and with food, you can have 2 and I'll take one package.  I have two very hungry boys!'
Utterance: 'Is there a reason you want the 2:1 split? Food my group's largest priority by a large margin (We eat a lot). It's worth a lot more to my group then the firewood would be.'

A:
Yes
