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 can't give out all the water. I need to be hydrated as well. ' 'You already have all the basics, though, so you won't lack sufficient water to be hydrated. I have a serious medical condition that requires that I have access to additional water. ' 'The maximum bundle I can give is all packages of food + 1 package of water'
Utterance: 'Sorry, that won't work for me. I've already said that I have a medical condition that requires additional water. You do not need that much water just to be hydrated -- you already have basic water. I can give you all of the firewood, but I need all of the water. '
Yes

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. I am also looking for water. I need it to cook our food and it is going to be extra hot and I need to keep my family hydrated'
Utterance: 'May i atleast have 2? I can get siezures if i dont get enough hydration'
Yes

Context: 'Good, but in shortage of some stuff.' 'likewise! what do you need?' 'I would be ok if you gave me 3 water, 2 food and i will give you all the firewood.'
Utterance: 'that doesn't work for me. I, too, am in need of water'

No
