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: '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'
Example Output: Yes

Example Input: Context: 'Sorry, that can't work for me. Is there a reason you need all the firewood and food?' 'I have health issues, and I need to keep warm at night.  And I don't know how much fish I can catch.' 'Okay, that makes sense. But I also need to keep warm.'
Utterance: 'I think I can get by with 2 firewood, and give you 1.'
Example Output: No

Example Input: Context: 'Hey there!' 'Hi! What are your preferences? ' 'Food is of the highest preference for me! I am a diabetic and always need to be able to eat if I'm experiencing a low! How about you?'
Utterance: 'Food is also my highest preference, followed by firewood, with water being the lowest. I don't have a medical condition that needs food so I can give you 2 units if I can have 1?'
Example Output:
Yes
