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'm fine, let's talk about how we can come to a fair deal.' 'Sure, my number one item if food if you can spare any.' 'It'd be nice if we can both get an even split right?'

No

Context: 'Yeah I'm hoping to relax with my family and enjoy the outdoors ' 'Same, i do ask though as i have a medical condition if i can have all the water, it is really hard for me to stay hydrated' 'oh that is tough.

Yes

Context: 'Hi, I would like two firewoods and two food. You can take everything else. Does that work for you?'
