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: 'Good afternoon, how are doing today? Let's get this thing going. What items are you most interested?' 'Hello , i am well. i dont need much so i would say an equal amount.' 'I have a medical condition that require me to drink a ton of water. I also can only eat certain foods and I have 3 kids. The more food and water the better for us.'
Utterance: 'sorry to hear that. i too have kids but my health is ok so i can do with 1 water.'

Answer: Yes


Question: Context: 'Wood is my highest priority. I need it to stay warm. I'm very cold-natured. What is your highest priority? 🙂' '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' 'I understand that. I also need food though, because I need the sustenance to help warm me up. So maybe 3 firewood 1 food and 2 waters for me?'
Utterance: 'I still don't think that is too fair though, since you would be getting 6/9 of the extra items and I would only be getting 3... I'm not an avid camper so I need extra amenities to make sure I survive haha. I am flexible on the water though - maybe we can compromise there. I am fine with you having all of the wood. Maybe we could give you 3 firewood, 1 food, and 1 water?'

Answer: Yes


Question: Context: 'I have to get food as high while water is low.'
Utterance: 'Ok, I have enough food, but I need firewood to keep warm and water because one of my containers leaked.  So, why don't you take all the food and I get everything else.'

Answer:
Yes
