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 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?' 'I know how to filter water so you can have all of the water. I would like as much firewood as possible.'
Utterance: 'me too. I don't care about water since we are camping near a river.'

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. 😡'
Utterance: 'Oh ok, well I plan on bringing some juice, beer and other drinks. So I could spare some extra water. And I am pretty good at fishing, so I won't need much food either'

SOLUTION: Yes

PROBLEM: Context: 'Welcome to the camping trip Dude!' 'Welcome! I'm really concerned about our water supply, we are desperately low. We don't have much food, a few protein bars. how are things looking your way?' 'I haven't got too the site yet but I am almost there.  I can't wait to finally relax!  I have been going nonstop for days.  Good idea to check supplies!'
Utterance: 'We're nearly there and just realized that we must have missed picking up some of our stuff before leaving.'

SOLUTION:
No
