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: 'I need more firewood to keep my food going.' 'I get it, in that case I'' take additional packages of food.' 'I don't think so, because I need additional packages of food in case there is an emergency.'
Utterance: 'I was under the impression you don't have the need for additional firewood as you mentioned you need additional of food and water. Let me know how many packages of item you need.'

Answer: No


Question: Context: 'I am so excited to go camping!  I am planning a nice long walk in the woods to decompress from the hectic days of working.' 'I am too.  I've been thinking of this since COVID.  I hear we have some materials to share between the two of us.  What are you thinking?  For me, I am from the South so I get cold easily 🙂 so firewood is my main priority.' 'Perfect!  I'm a northerner, so the firewood is all yours!  I'll need lot's of water to keep hydrated after the hike, and I'll probably be pretty hungry too.'
Utterance: 'My spouse calls me a water buffalo so I'm pretty water dependent if you couldn't tell.  '

Answer: Yes


Question: Context: 'Okay. Lets just try to do some negotiation. I am the most interested in getting more WATER. The water I already have at the campsite looks dirty so, if it is okay with you, I would like all THREE of them. My food has also been stolen by bears and I don't make much left, so I would like TWO of the food items. You can have all the firewood and the other food item. How does that sound? 🙂' '😮Sound good enough but since you know i can not do without having anything to sustain me whenever i am thirsty then i suggest you are free to take TWO of the water and since your food has also been stolen by bears and you don't make much left, then you can have the TWO of the food items too and leave the THREE firewood for me with ONE food. How does that sound? 🙂' 'I think we are getting very close to a good deal. Would you be willing to give me ONE firewood in case the stuff I have gets wet?'
Utterance: 'I strongly agree and shall we call it a deal now? 🙂'

Answer:
No
