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.

[Q]: Context: 'Hello 🙂' 'Hello to you!' 'Food is the most important item for me because the food I brought has spoiled! Which item do you need the most?'
Utterance: 'I need water above all else.'
[A]: No


[Q]: Context: 'Great, we can split the food, how are you on water?' 'That would be great. I need to have frequent small meals throughout the day so the extra food would help. I have plenty of water. ' 'alright, so I'll keep the water, and firewood, and give you 2 extra food.  Does that sound like a good deal?'
Utterance: 'I actually need one firewood and one food package. I can give you one water. '
[A]: Yes


[Q]: Context: 'i hope we can come to a compromise 🙂, what is another priority of yours besides the wood?' 'Food is a second priority for me, as I will be metal-detecting as well, & cannot risk fainting from the heat. How about I give you two firewood (I don't think we can "share", haha), you can give me two food packages, and two water packages.' 'okay, I am willing to give up more food to get the firewood, I like your offer🙂'
Utterance: 'I do as well. I'm glad we could come to an agreement! 🙂'
[A]:
No
