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: 'Hi there, how are you doing?' 'I am great. Excited to go camping. How much food do you need?' 'I could use some extra food, I'll be hosting a get-together at my campsite later and will need some to entertain the guests. I'd like 2.'
Utterance: 'That is fine. I can go fishing to get some extra food but I would still like one. Can I take two packages of firewood so I can cook them? '

Answer: Yes


Question: Context: 'I will be camping for 3 day so I gotta have some food.  Although, I do understand your situation.' 'I see. Yeah, if any of us knew how to fish or forage, we wouldn't need as much, but we're all from the city, so our survival skills are pretty bad and we're going to be camping for almost a week. But I get that fish aren't super reliable for food either... ☹️' 'I understand.  So we have came to an agreement that I get 2 water, 1 firewood, and 1 food, is that right?'
Utterance: 'Yeah, that sounds good to me. Thanks for being understanding. I hope your camping trip goes well.'

Answer: No
