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: 'so If I understand correctly, the Deal is I get 3 Food and 2 Water: While you get 3 Firewood and 1 Water?' 'I was just negotiating the water for now.  I was trying to do one at a time.' 'ah, I'm definitely ok with doing one at a time: A 2:1 split is definitely OK with me: The issue is, if we consider each individually, it might be harder to come to a deal, but I'm happy to do it your way.'
Utterance: 'How about you take 1 firewood, I''l take 2 and with food, you can have 2 and I'll take one package.  I have two very hungry boys!'

Answer: No


Question: Context: 'That's fair, but I have wiggle room on the water, how about I take two food, two firewood and you take 3 water, 1 food, 1 firewood?' 'Is there anyway you will go with that I get two firewood? I need food the most but since you get most of that can I get most of the firewood? So 1 food, 2 firewood, and 2 water for me?' 'You drive a hard bargain. I could really use that firewood. It's going to get cold tonight and these sleeping bags are not worth the price I paid ;)'
Utterance: 'Haha, I know but I am in the same situation! ☹️ and since I am getting less food I feel like it is fair I get on more firewood since I truly need that 🙂'

Answer: No


Question: Context: 'Since I'm most interested in firewood, I would want 3 waters if you're going to get more firewood.' 'Nice. That's okay with me. You get 3 waters and a I get 3 firewood' 'I was actually saying you get 2 firewood and I get 3 waters. Then you could have 2 food and I get 1 food.'
Utterance: 'That's seems fair to me since we all need food to eat'

Answer:
No
