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.

Context: 'me and my gals thing that firewood is important also but we actually want water' 'We can figure something out. Would you rather have 3 water and 0 firewood or 2 water and 1 firewood?' 'can i have 2 foods too'
Utterance: 'If I can have all the firewood...'
No

Context: 'I am most interested in water! My husband and I are traveling with our newborn and we need as much water as possible!🙂' 'Ah, I see! I am in the same boat. We are camping somewhere where there is no source of water and it's very hot. Hm, let's see how to go about this' 'what else is a priority for you?'
Utterance: 'Firewood is definitely important as well! Last time I went camping we ran out pretty fast, so I want to be extra prepared. 🙂'
Yes

Context: 'I have enough food too. Can I take 2 water, 1 firewood and 2 food?' 'How about two water, 1 firewood and 1 food, since we both value water the most?' 'Is that what you want or what you are offering?'
Utterance: 'That's what I'm offering to you, but I think it's a fair deal, so I'd accept it myself, too.'

No
