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: 'I like firewood and water most' 'Hmm okay, I am willing to give you three waters! I was hoping to get 3 firewood though, as it's going to be really cold where I am going.' 'seems like we have same priority items. firewood. I also need firewood most because I am prone to pneumonia '
Utterance: 'Oh no, I'm so sorry to hear that ☹️ Let me ask about the food first then, would you be willing to give me the 3 packages of that? I am going to have a lot of people with me and we won't be near any stores at all.'
Yes

Context: 'Well, I do need some of each, what about I take 3 food and 1 each of the other two?' 'I don't mind taking 2 of the water as I need it for a medical condition and 2 firewood however I would like to get 1 of the food.' 'You need water the most?'
Utterance: 'I am constantly thirsty and having water on hand is needed. Why is gathering food an issue for you?'
Yes

Context: 'I need the water to drink - I don't trust the water I might find at the campsite.' 'Did you bring any water to start?' 'Yes! Did you bring any food to start?'
Utterance: 'I did, but my friend only feels comfortable with extra around, God forbid, if something happens this could save his life. So I'm thinking, I take all three food packages, two firewood packages and leave all three water and one firewood for you. '

No
