TASK DEFINITION: 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.
PROBLEM: Context: 'Hmm, okay, that sounds reasonable. How does 3 water, 2 food and 1 firewood for me, and all the rest for you sound?' 'Im goign to need all the firewood I can get. They want to cook smores on it. How about you get 3 water 2 food and I get 3 firewood and 1 food. I think that is very fair and would help us both out. 🙂🙂' 'That sounds like a very reasonable deal, I understand how girls can get with their snacks haha. I'm okay with giving up all the firewood. You said you need at least some of the food, right?'

PROBLEM: Context: 'Uh oh. What are you preferences on supplies?' 'food, then water, then firewood, and yours?' 'water, food then firewood. It's really hot so I need to make sure we are hydrated. We forgot a bag of supplies that had mostly food so we really could use food. It's hot so firewood isn't necessary. If anything we can get it from around or on a hike.'

SOLUTION: No
