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: 'I can't do that. Truth is I need the firewood and I was hoping you didn't need it. I propose I keep 1 firewood, 3 waters and 2 food and you take the rest?' 'I would do this instead: 3 firewood, 1 water and 2 food.' 'That's not going to be a fair offer, you'll need to do better than that or I don't think we can come to an agreement'
Utterance: '3 firewood, 1 water, 0 food'

Answer: No


Question: Context: 'I'm doing well. I'm looking forward to going on my camping trip but will need some additional items to make sure the trip is safe, healthy, and enjoyable. ' 'Same here. ' 'I have diabetes, so it is very important to me that I get extra packages of water and food. When I'm at home, I always need to pack extra drinks and snacks for myself in case I go into shock and need to take medication. The trip could be very dangerous for me if I don't have access to these additional supplies. '
