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 fellow camper! I am interested to know your preference in items?' 'Hello! Yes I'm excited for the trip. 🙂 My most important is food. How about you?' 'I am excited too. I really need food too. What other item is priority for you?'
Utterance: 'I also need water because we plan to do a lot of hiking. What about you?'
answer:
Yes

Context: 'Hello - I would love be able to split some supplies with you🙂. I could use some extra firewood so maybe i could take 3 and maybe you could have some extra food? ' 'Maybe I could take 2 firewood 2 food and 0 waters?' 'I was planning on staying up all night and keeping my fire going all night.  Honestly I could give you all the extra food if that helps you if I could please have the 3 firewood?  We could split the waters'

Yes
