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.

Example Input: Context: 'I will need 2 firewood, 2 water and 1 food'
Utterance: 'How about you take all the firewood because I have the skills necessary to chop down more. I also will need three packages of food because I will be climbing a very tall mountain.'
Example Output: Yes

Example Input: Context: '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.' 'Oh, I see. Well, I personally need lots of water to stay hydrated since I drank a lot already.'
Utterance: 'Yes, that's important. I don't need much.'
Example Output: Yes

Example Input: Context: 'I'm great! Me too! did you have any specific plans? I wanted to make an extra fire to cook with and cook a nice meal. ' 'Yes. I'm actually taking a large group of people. Some friends and family are going and I kind of also wanted a bit of extra firewood. 🙂' 'Oh I get that! I wanted to make a nice meal for my friends so I was hoping to be able to get extra food. 🙂'
Utterance: 'Oh well that's no problem. I'm packing a lot for our group. I'd be willing to give you all the food if you give me all the firewood?'
Example Output:
Yes
