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: 
Utterance: 'Hi how are you? I have a few medical issue and do need to stay warm so fire wood is important to me. What is important to you? '

SOLUTION: Yes

PROBLEM: Context: 'Hello' 'Hi there.. how are you doing today?  I hope well!  🙂  So, it looks like we need to divy up these supplies, huh?  Do you have any thoughts on the issue?'
Utterance: 'I'm doing fine thank you, how about you? Well for my trip I'm most interesting in socializing so a great campfire a night would be great, I'd prefer not to boil water either so want extra of that too. Food less so as I will go fishing and know wild vegetables, fruits and mushrooms I can pick. How about you?'

SOLUTION: Yes

PROBLEM: Context: 'So let's make sure this is reasonable; Firewood - 2 for me, 1 for you; Water 2 for you, 1 for me, and you can have all of the water?' 'sounds good. 1 firewood for me  2 food for me and i can have all water. to clarify. sorry about typos' 'No worries, ok that sounds good; I'm going to submit the deal.'
Utterance: 'nice 🙂'

SOLUTION:
