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: 'Hi there, I am doing well, I can get you an extra firewood as long as I can get extra Water and Food to thrive during camping' 'I would be ok with that but i will need some water and food as Im a little out of shape' 'I can get you one package of water and food, will that work?'
Utterance: 'how am i supposed to stay alive with one package of food and water im fat lol'
Yes

Context: 'Hi there! I'm so excited to be going camping this weekend. I haven't been able to do anything because of the pandemic. Do you have any plans for the weekend?' 'No, I don't have any plans for this weekend. Can we camp together?' 'If you want to tag along, sure. lol I'll be heading to the mountains so it's going to be hot during the day and cold during the night.'
Utterance: 'Great, hey, I'll make you an offer, I'll keep 3 firewood, 3 food and...'

Context: 'I can't wait 🙂 Let's talk about these supplies. I've got hungry mouths to feed, Can I take the food and you can have half the firewood and all the water?' 'Hmm, I need food too. I am willing to split. I will give you 2 food since you claimed it first. Can I have 2 waters then?' 'That's fair, but I have wiggle room on the water, how about I take two food, two firewood and you take 3 water, 1 food, 1 firewood?'
Utterance: 'Is there anyway you will go with that I get two firewood? I need food the most but since you get most of that can I get most of the firewood? So 1 food, 2 firewood, and 2 water for me?'
No
