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 Q]: Context: 'How many wood do you think you need?' 'I would like 2 of the firewood. What do you think? ' 'I don't need wood as I am usually warm so I think we can work out a deal. I like to have more water and I usually get thirsty.'

[EX A]: No

I am really looking to get extra firewood, so I would like to make a compromise. If I gave you all the food, could I have more firewood?' 'I like watching the camp fire all night. What is your reason for needing more firewood?'
