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: '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?' 'Hi, I need the all food package. I will frequently feel hungry'
Utterance: 'I can give you two of the packages if you're willing to give me all 3 of the firewood. I left mine out in the rain a couple of nights ago so its all ruined.'
answer:
Yes

question:
Context: 'That doesn't really work for me because then I would get only 2 waters and nothing else ☹️. What do you think is your highest priority?' 'Wood is my highest priority. I need it to stay warm. I'm very cold-natured. What is your highest priority? 🙂' 'Oh that's good. Wood is not my highest priority since I get hot easily lol. My highest priority is probably food because I have a very high metabolism and get very hungry'
Utterance: 'I understand that. I also need food though, because I need the sustenance to help warm me up. So maybe 3 firewood 1 food and 2 waters for me?'
answer:
Yes
