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: 'How are you enjoying the camping trip so far?'
Utterance: 'Hi. It’s great, but very cold here. How about you? '

SOLUTION: Yes

PROBLEM: Context: 'Oh no, that's not good.  I still have some left over, but we're running out of firewood to use to heat it.' 'Seems like we are in the same boat, the bear tore our tent to shreds so we are sleeping outside and it is cold☹️' 'Sounds like a rough camping trip.  It has been pretty cold lately.'
Utterance: 'Is it possible I could have 3 food since I have none and 2 Firewood to stay warm and you can have 1 Firewood and 3 Water?'

SOLUTION: Yes

PROBLEM: Context: 'I do agree with that, I am happy with all of the extra water, and I should be able to get more firewood pretty easily, and since you will be sharing whatever food you find, I think that we came up with a pretty fair split.' 'It's always lovely to have a camping companion you can cooperate with! ' 'I completely agree and i am glad that we could work together and compromise.'
Utterance: 'Absolutely! I am sure we will be able to find a good spot with some firewood around! I always bring my axe, so I will let you borrow it to chop wood around camp. This is also a great season for mushrooms to be growing! That would make a great side dish to the fish! I love sauteeing them over a hot fire! 🙂'

SOLUTION:
No
