instruction:
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.
question:
Context: 'Hi there.  I'm hoping we can make a deal about me getting firewood.  I get really cold at night and I'd love to have my fire still going in the morning for coffee - I'd gladly share some if you pop by my campsite.' 'I am in dire need of firewood myself. I was planning on bringing food that needed to be cooked over flame. 😮' 'Well maybe we can find a way to split it!  This isn't a problem we can't solve.  Are you in need of food too, then?'
Utterance: 'That would be great! I don't need food as much as I am in need of firewood, to be honest.'
answer:
No


question:
Context: 'I'm doing well. I'm looking forward to going on my camping trip but will need some additional items to make sure the trip is safe, healthy, and enjoyable. ' 'Same here. ' 'I have diabetes, so it is very important to me that I get extra packages of water and food. When I'm at home, I always need to pack extra drinks and snacks for myself in case I go into shock and need to take medication. The trip could be very dangerous for me if I don't have access to these additional supplies. '
Utterance: 'Actually mine own purposeful need is firewood and water. Being on a first time adventure, I lack these items as I was inadequately prepared.'
answer:
Yes


question:
Context: 'I'm going to need some extra wood because I'm somewhat injured and can't really gather more.' 'Oh, I see. Well, I personally need lots of water to stay hydrated since I drank a lot already.' 'Yes, that's important. I don't need much.'
Utterance: 'The thing I need less, but still sort of want some of, is food.'
answer:

Yes
