Definition: 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.
Input: Context: 'I agree. What supplies could you use more of?' 'Water for sure, need to stay extra hydrated.  How about you?' 'Haha yup I had a feeling about that one. ;-) Yeah my wife has a bunch of crazy hikes planned so water is a must here too. What else?'
Utterance: 'Food of course, always snack more when relaxing.  Agree on the hiking.  Out in the woods, we won't have to wear masks!'

Yes
