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: '😮Sound good enough but since you know i can not do without having anything to sustain me whenever i am thirsty then i suggest you are free to take TWO of the water and since your food has also been stolen by bears and you don't make much left, then you can have the TWO of the food items too and leave the THREE firewood for me with ONE food. How does that sound? 🙂' 'I think we are getting very close to a good deal. Would you be willing to give me ONE firewood in case the stuff I have gets wet?' 'I strongly agree and shall we call it a deal now? 🙂'
Utterance: 'Like I said, we are close but I really would feel better with just one of the firewood. I'm afraid of not being able to build a fire. If you really need the firewood, however, then I would take one additional item of EITHER the water or food instead.'

SOLUTION: Yes

PROBLEM: Context: 'Good afternoon, how are doing today? Let's get this thing going. What items are you most interested?'
Utterance: 'Hello , i am well. i dont need much so i would say an equal amount.'

SOLUTION: No

PROBLEM: Context: 'OK. Are you need Extra food packages?' 'no, I am okay with food which is why I offered them all to you since all my firewood is ruined. I figured if i gave you 2 water and 3 food you might be able to spare the 3 firewood' 'No I cant give you all the firewood. I will take atleast one firewood. Also can I have all three water bottles. '
Utterance: 'the absolute most water I can spare is 2 and , my firewood is pretty much useless. I can give you 2 water and 1 food for 2 of your firewood that is my final offer'

SOLUTION:
No
