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: 'That's good to hear, you always have to be careful with wild water though, it has all kind of germs. Sounds like you'll have plenty of dry firewood though. ' 'Yes, I would be willing to let you have all the firewood for 2 of the cases of water. How much food were you needing?' 'I like your water and firewood arrangement. Can I have 2 of the food since you're getting 2 of the water? '
Utterance: 'Let me think on that. I know there won't be much for berries or small animals to hunt for. Is where you are going have much available for you to hunt and scavenge for?'
answer:
Yes

question:
Context: 'Firewood, due to the area that we are going to. How about you? ' 'Oh I see. You can have all 3 firewood if you are ok with me taking all 3 food.' 'Hmm, well I'd love to get some of the food. What I took 2 firewood, 1 food and 1 water? '
Utterance: 'Sorry but I really need all 3 food. All the food I brought with me has spoiled because the AC in my car broke. ☹️'
answer:
Yes

question:
Context: 'Is there anyway you will go with that I get two firewood? I need food the most but since you get most of that can I get most of the firewood? So 1 food, 2 firewood, and 2 water for me?' 'You drive a hard bargain. I could really use that firewood. It's going to get cold tonight and these sleeping bags are not worth the price I paid ;)' 'Haha, I know but I am in the same situation! ☹️ and since I am getting less food I feel like it is fair I get on more firewood since I truly need that 🙂'
Utterance: 'Some extra water for coffee might keep us warm, would you consider taking 1 food, 2 wood, 1 water?'
answer:
Yes
