instruction:
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.
question:
Context: 'just a bunch of children under 5 who wont be able to gather firewood. so i desperately need at least 2' 'I see, well it sounds like you're going to need some additional food with those children. How about I provide you with some additional food and you can help me with my need for heat with firewood?' 'okay how i take all 3 food and 1 firewood?'
Utterance: 'The firewood sounds like a solid deal; I would need a little food though to assist me. The good news is since there's a stream near me, I won't need any additional water, so I am happy to provide you with all of the additional water.'
answer:
Yes


question:
Context: 'I would like water more than food. ' 'How many wood do you think you need?' 'I would like 2 of the firewood. What do you think? '
Utterance: 'I don't need wood as I am usually warm so I think we can work out a deal. I like to have more water and I usually get thirsty.'
answer:
Yes


question:
Context: 'Ok me too! I am concerned the most with firewood as it is the basis for my camping activities: campfire, story telling, and producing heat. ' 'OK so how about you take 2 firewoods and 1 food' 'That works for me. May I have two waters since I have more of a need of water'
Utterance: 'That works for me since I have the filter!'
answer:

Yes
