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 also need more firewood.  I thought I would be able to find enough around the campsite but I guess that rain got us both 😮' 'yeah, horrible way to start the trip but I am sure it will get better. if i can have 2 of the fire wood you could have all three of the extra water' '🙂 Okay, I'll consider that since I do need some more water.  How should we split up the food?'
Utterance: 'well if your getting all 3 food and 1 of the fire wood how about i get 2 food and you get one? then it is more or less even'

SOLUTION: No

PROBLEM: Context: 'hello how are you' 'i'm good thank you, How are you doing today?' 'I am good, let's plan our camping trips. I am diabetes, so water is very important to me. what about you?'
Utterance: 'I need water too'

SOLUTION: No

PROBLEM: Context: 'Hello, how are you doing today?' 'Hey there, I'm doing well! I'm excited to choose camping supplies.' 'Me too🙂. I packed a lot of food so I have plenty to spare'
Utterance: 'that's awesome. I think I need more food myself, but I have tons of water.'
