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: 'yes we can' 'Ok, could you tell me which item you need more and which one you need less?' 'i will be needing more of water '
Utterance: 'Okay, what I need most is food because I need nutrients, could you tell me what is the least you need?🙂'

SOLUTION: Yes

PROBLEM: Context: 'Oh, I see what you did there. No problem I have plenty of firewood for you buddy. 🙂' 'Great! What extra supplies would you like to bring?' 'Since it's hot there, I get thirsty and dry real quick. 😡'

SOLUTION: No

PROBLEM: Context: 'Hi we would like you to consider giving us all of the rations for the trip.'
Utterance: 'hello, that could be a good idea, but I think I need more rations'
