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.

[EX Q]: Context: 'That is a promising bargain but I want at least 2 firewood, it makes for a fun time for my group.' 'Interesting , because my group feels the same way though. How does your group feel about water though?' 'Water is not that important for us but the firewood is a deal breaker for us ☹️'
Utterance: 'I see.... Well we really would like the firewood too though. Could you reconsider it makes a big difference for us.'
[EX A]: Yes

[EX Q]: 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? '
[EX A]: Yes

[EX Q]: Context: 'Oh, that's not possible.  Sorry☹️' 'Sry for the extra emoticons, laptop's glitching apparently. Well, what can you give me or we come to a deal on? 🙂' 'Well, let me think on that.  Why do you need so much water for a starter?'
Utterance: 'I get dehydrated easily. I need to water so that doesn't happen. 🙂'
[EX A]:
Yes
