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: 'I just want to make sure that I don't run out. I will have my kids with me and need to make sure they don't get too cold 🙂' 'Understandable I am an avid outdoorsmen; Starting firewood is hard and can also be dangerous; how about you give me the two I will only use one you get one and I will be able to secure more within a few hours. ' 'Are you sure that you would be able to get more firewood on your own?'
Utterance: 'Yes and as a return ill give you 70 percent of what I get-- So with me managing the firewood for you, you will get more time with the kids.'

SOLUTION: No

PROBLEM: Context: 'No me gusta mucho el trato, pero para eso debemos hablar y decidir como adultos un buen trato para los dos. Lo que queremos es disfrutar en el campamento.' 'I do not understand spanish. Please speak to me in English.' 'Sorry I'm practicing my Spanish for the camp. I do not like the deal very much, but for that we must talk and decide as adults a good deal for both of us. What we want is to enjoy in the camp.'
Utterance: 'By giving you all three food and 2 of the three firewood, you're definitely getting much more than I am.'

SOLUTION: No

PROBLEM: Context: 'Hi! I'm very excited for the upcoming camping trip!! 🙂' 'Me too! 🙂 What do you think about the extra supplies?' 'I recently bought two new puppies, and they are coming on the trip. I could really use the extra water for them!'
