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 just want to make sure that I don't run out. I will have my kids with me and need to make sure they don't get too cold 🙂' 'Understandable I am an avid outdoorsmen; Starting firewood is hard and can also be dangerous; how about you give me the two I will only use one you get one and I will be able to secure more within a few hours. ' 'Are you sure that you would be able to get more firewood on your own?'
Utterance: 'Yes and as a return ill give you 70 percent of what I get-- So with me managing the firewood for you, you will get more time with the kids.'
No

Context: 'I was going to say, the fire would be probably one of the few things I would be interested in! I love being warm.' 'Well you can take all the firewood if it will help, would it be ok if i get all the food in return?' 'That works for me. How would you like to divide the water?'
Utterance: 'I am ok with you taking two waters since you are new to camping, does that seem fair to you?'
No

Context: 'I would like to take at least two of the food items because I get sick easily and faint if I do not have enough food. You can have two of the waters but I would like one. '
Utterance: 'yes i could take two of the foods because i i leave some of mine. thank you'

Yes
