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: 'Nice! What are your highest priority items?' 'We need a moderate amount of everything and I think we can work something out successfully.' 'got it, OK I'll start then. I'd like at least 2 firewood'
Utterance: 'Okay. we brought some of our own food so I don't need much of that either.'
Example Output: Yes

Example Input: 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.'
Example Output: No

Example Input: Context: 'Hello, I hope we can work together on an offer that benefits both of us. Do you think it's OK?🙂' 'Yes definitely!  I am pretty easy to work with and would like a deal that will help us both out as much as possible.' ' The item I need the most is water because I need to hydrate to stay strong and achieve my goals. And you?'
Utterance: 'I would say water as well because I am very active and build up thirst as a result.  However, I would be willing to compromise on things to allow you to have more water.'
Example Output:
No
