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: 'I have a medical condition that causes my veins to close up when I get too cold. I will thus need the 3 firewood.' '☹️Oh, that sounds awful. Are you sure you need all three packages of firewood?'
Utterance: 'I might be able to get by with just two... I'm on a diet though, so I don't need as much food.'
answer:
Yes


question:
Context: 'I don't mind the division but I would like a pack of firewood added because my family of 7 consume this item as well during the day & night' 'you would have to give more items up to get firewood. if you get more water, which is our highest item, i need more of other items' 'How about 1 water, 2 food and 2 firewood?'
Utterance: 'I don't really need food, to be honest. Food is the least of my worries.'
answer:
Yes


question:
Context: 'Good!  How are you?' 'I'm doing well! Almost ready for my camping trip. Need some more supplies though.' 'Which supplies do you need?'
Utterance: 'Well, I really need water in case we get really thirsty from hiking. I also need firewood in case it gets colder and we need more. It would be cool to have more food added for dessert like s'mores, but it's not really necessary.'
answer:

Yes
