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, I'd like 3 packages of food. I have diabetes and my blood sugar could drop.'
Utterance: 'oh dear, I am sorry to hear that my son is type one, I am okay with giving you all the food if you could give me all the firewood. I have hypothyroidism and it makes me get cold.'
answer:
Yes

question:
Context: 'Interesting. If I decided to forgo water completely, would you accept giving me everything else?' 'no, at the most i can do is i get 2 water, 2 food and 0 firewood or I get 1 water, 3 food and 1 firewood' 'But you get everything you wanted. You said you needed 3 water, I offered it to you.'
Utterance: 'but i can't give you 3 food and 3 firewood, thats 6 items vs the 3 water'
answer:
No

question:
Context: 'Food is actually my first priority but since it seems to be first priority for us both I thought we could split that. Water doesn't seem to be a priority for you so thought I could take that' 'My first priority is actually firewood. Food is my second. 🙂' 'Okay so would 2 firewood for you and 1 for me work, and 2 food for me and 1 for you?'
Utterance: 'I can definitely agree to that. What was your second preference? Water was my third.'
answer:
No
