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.

Ex Input:
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! 🙂'

Ex Output:
No

Context: 'Good how are you' 'I am doing quite good. I enjoy camping. I however did not bring enough food.' 'Ok I'm sure we can work it out because I know I need extra water and firewood. Do you have any ideas on how to divvy up the extra supplies?'
Utterance: 'I would need some firewood as well, as I need it to cook the food. I was thinking maybe you can have all the water and I have all the food.'

Ex Output:
