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 would really like some extra firewood to keep the chill off on those cold  nights.🙂' 'Me too. It has been rather cold lately! But I am also really interested in water.' 'I don't need the water as much.  How about I get 2 firewood and you get 2 water?'
Utterance: 'I would prefer all the water. You can have all of the firewood.'
No

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.'
No

Context: 'Hi there. I was really hoping to have the firewood because I am afraid my children would be cold.' 'Ok, so we have 3 packages, what about if you get 2 and I get 1?' 'Thank you, 2 packages of firewood would work.'
Utterance: 'So could I get 2 food, if you get 1 food?'

No
