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 am going to be camping for a couple of weeks, so I will need quite a bit. I also realized some additional water would be good, because I have some meals that need me to boil water. Maybe you can have 2 firewood in exchange for me having one of your waters? Then you would still have plenty of water, but also plenty of firewood 🙂' 'So sorry, I just realized you did not agree to the 3 waters in exchange of 3 foods. if you want a water, i will also will need one food. just to make things more fair on my end. If not i am looking at 2 waters, 0 foods, and 1 firewood. But i am willing to compromise for 3 waters, 1 firewood, and 0 foods. and you'll get 3 foods, 2 firewoods, and 0 waters, what do you think?' ' I appreciate your willingness to discuss this, so we both get a fair deal. I would really like if I get 3 food, 1 water, and 1 firewood. Then you would get 2 water and 2 firewood. You said that you really need water and food, so I think that would work best for both of us to get what we need most. What do you think? 🙂'
Utterance: 'Np, problem, water is high in demand on my end with the amount of kiddos I am taking. Water is my main concern, will you be okay with 3 Foods, 2 Firewoods and no water?'

Answer:
No
