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.

Input: Consider Input: Context: 'Of course! Are you going camping too?' 'Yes.  I have 2 children so I was thinking that I will need extra water. 🙂' 'I too need extra water, but I'm willing to negotiate on the other things if you are! 🙂'
Utterance: 'If I take 2 waters, will you accept 2 firewood?'

Output: No


Input: Consider Input: Context: 'Hello, how are you? Looking forward to camping?' 'Oh yeah, that's for sure. What camping item do you prioritize?' 'I'm going to need some extra wood because I'm somewhat injured and can't really gather more.'
Utterance: 'Oh, I see. Well, I personally need lots of water to stay hydrated since I drank a lot already.'

Output: No


Input: Consider Input: Context: 'Hey there - looks like we are both going camping!  I'm from the South so firewood and water are a high priority for me.' 'Wow, thats awesome! Yes, I am! Well, that's great because water isn't super important for me. Firewood is though. '
Utterance: 'That sounds awesome - I'm sure we can come to an agreement on how to allocate that works for both of us.  '


Output: No
