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: 'hello' 'Hey! How are you? My bestie and I were going to be going on a camping trip, but my other friends heard about it and wanted to come along so we're going to need more supplies than I initially though which has got me a little worried. ☹️'
Utterance: 'Yes!!! I need some water pretty bad.  I am good on food because I fish and I have been able to catch some catfish from the lake.  How about I take 2 water 2 firewood and 1 food'

SOLUTION: Yes

PROBLEM: Context: 'Hi! I'm exited to negotiate a deal with you today. How are you doing?' 'I am doing well! Excited to be on this camping trip! I am glad we have all the basic supplies already.' 'Agreed! I am running low on firewood, unfortunately, which I need to cook food and stay warm. '
Utterance: 'Oh no! That's unfortunate! Luckily, I think I have plenty of Firewood for myself so I think it would be okay for you to have more of that if needed. I don't know if I have enough food. I love to snack all day!'

SOLUTION: Yes

PROBLEM: Context: 'Hello.  I hope you are well.  I would like to have all of the water, 2 of the firewood and 1 of the food.  ' 'Hello.  I'm actually not doing too well.  There have been a few problems and I will need some of the extra packages.  I'll need two of the waters, 2 of the firewood and 2 of the food.' 'I'm sorry to hear that you are not doing well.  I've also have some issues.  On the way up to the camp site, all of my clean water spilled in the car.  I was really hoping to be able to get all of the available water.  Why aren't you well?  I hope it's not serious.  ☹️'
Utterance: 'Oh, that's terrible.  I'm sorry that happened.  I need the water for my child.  They seem dehydrated and disoriented.  My husband has also caught a cold and has been having chills.  I thought the extra firewood would help him feel better.'

SOLUTION:
No
