Detailed Instructions: 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.
Q: Context: 'Ok, although I was thinking that I could probably find some firewood, but would prefer more water so I don't get dehydrated and can use it to wash and cook.  How about I take 1 firewood, 2 water, and 1 food' 'Good thought on finding your own firewood.  I appreciate the offer of 2 firewood.  I can cut back on water for washing/cooking.  So how about I take 2 firewood, 1 water and 2 food' 'ok that sounds fine🙂'
Utterance: 'Great, thanks for understanding and working with me....and enjoy your first time camping🙂'
