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 no-need strategy, otherwise output No. no-need is a cooperative negotiation strategy. It is used when a participant points out that they do not need an item based on personal context such as suggesting that they have ample water to spare. no-need can directly benefit the opponent since it implies that the item is up for grabs.
PROBLEM: Context: 'I'm also going camping with my two children and 2 of my nephews  How would you like to divide the supplies?' 'Well what do you need the most of?' 'I need the most firewood due to a congenital issue that results in us having poor blood circulation to our extremities, thus making them susceptible to frostbite in the cold!'
Utterance: 'Oh dear, that sounds serious!  Well I need food the most because my children eat sooo much and I don't think I packed enough.  How about I'll give you all my firewood in exchange for all your food?'

SOLUTION: No

PROBLEM: Context: 'Got you! I really need firewood to make smores and I don't think we have enough to last the whole night!' 'I was hoping to pick up a lot of wood. It has rained around here and the wood is soggy in the forest.' 'Which item do you prefer the most?'
Utterance: 'I know how to filter water so you can have all of the water. I would like as much firewood as possible.'

SOLUTION: Yes

PROBLEM: Context: 'I did, but my friend only feels comfortable with extra around, God forbid, if something happens this could save his life. So I'm thinking, I take all three food packages, two firewood packages and leave all three water and one firewood for you. ' 'I think that it is fair that you get three food and I get three water, but why should you get two firewood to my one?' 'The food is not for me, I'm not allowed to touch it. t\The only real benefit I'm getting here is firewood. ☹️'
Utterance: 'OK,that sounds good. So you get three Food, I get three Water, and we split the Firewood, you get two and I get one.'

SOLUTION:
No
