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: 'Hello I'm really hungry and thirsty and want some food and water if that's ok with you. '
Utterance: 'Well some is okay but not all. The thing is that we left in a hurry and forgot to pick up the bag with the extra food items. I am sorry but we have kids with us so we will need the food. Am sure you understand ☹️'

SOLUTION: Yes

PROBLEM: Context: 'I will provide you the food, but I am asking only one for my people.' 'I am giving you all the water,  how come you need the food? ' 'The main reason is to prevent us from cold.  Please provide three wood and three water.  If this is okay, then I will provide you three food.'
Utterance: 'Food doesn't prevent cold. Thank you for giving me all the food but I need 1 wood to cook the additional food. You still end up with more items in the  end  '

SOLUTION:
Yes
