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.

[Q]: Context: 'Same here! Last time my daughter got dehydrated and it made her sick!' 'That sounds awful! 😮 Where are you going to be camping?' 'In Arizona, so I know it'll be hot. How about you? '
Utterance: 'Same! At least, I won't need firewood, because it will be so hot. I'm very worried about the water situation though. It's just going to be me out there and the only fresh water is at the base of the canyon, and that's a really long and dangerous hike down for one person.'
[A]: Yes


[Q]: Context: 'I would like to ask for 3 firewood, 1 water and 0 food. I will be in an area where no extra wood will be available and I need the wood to cook all the food that I will already have.' 'I understand where you're coming from but I'm afraid that is not acceptable.  My family's comfort is my top priority and I will be needing at least 2 firewoods to make sure they are kept warm.  I would also request some extra water. '
Utterance: 'I need a minimum of 2 firewood. You can have 2 water. I would now like 2 food.'
[A]: No


[Q]: Context: 'Hello, I am very cold and need food and wood to remain warm. How about I get 3 firewood, 3 food and 1 water?' 'That doesn't really work for me because then I would get only 2 waters and nothing else ☹️. What do you think is your highest priority?' 'Wood is my highest priority. I need it to stay warm. I'm very cold-natured. What is your highest priority? 🙂'
Utterance: 'Oh that's good. Wood is not my highest priority since I get hot easily lol. My highest priority is probably food because I have a very high metabolism and get very hungry'
[A]:
Yes
