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: 'Yeah. Nice to get out after being inside for most of the spring. This covid-19 crap! wish it would go away.' 'I agree!  I will say it has really sparked my interest in camping and being outdoors even more though! I saw just how connected I was to technology and everything else!' 'I'm up here to do some cross training and noticed that there is some extra water around. Even though the nights are cold I could use some extra water. Do you exercise much?'
Utterance: 'It has been extremely dry in the area I will be going to so I was hoping to get a little extra water too.  I do. I love hiking and running trails!  Due to the extreme dry weather I should have plenty of wood I can scavenge for if you need all of it!'

SOLUTION: Yes

PROBLEM: Context: 'Hey there how are you?' 'I am fine friend. I need a lot of firewood though. It is freezing' 'I definitely need firewood as well. We didn't anticipate it being as freezing cold as it is at night. There isn't much around us. We've also been using a lot of water, which we could use more of since we've been looking for firewood.'
Utterance: 'Your needs are like mine. I have a condition that require  me to shower quite often. It is a shame but if I do not shower for 3 hours I will stink.  '

SOLUTION: No

PROBLEM: Context: 'Ok so I propose 2 water for me, 1 for you. 2 food for you, 1 for me. Firewood would be, 2 for you, 1 for me? Please give me your opinion if you want to reverse any of that.' 'That would work, the extra firewood would offset the need to have water on hand when I can boil it.' 'Just take one more minute to make sure you are good with that and let me know. As soon as you are absolutely sure, I will send the proposal.'
Utterance: 'You need the water more I feel. I don't want to slight you for having a medical condition and I know how the heat can take a toll on people. I think that proposal works well enough as I'm getting extra firewood and food. '

SOLUTION:
No
