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: Context:
Utterance: 'how about I give you 2 waters and 1 food package in exchange for all your firewood?'
Example solution: No
Example explanation: The utterance does not use the no-need strategy since it never refers to an item that the participant does not need.

Problem: Context: 'I am so excited to go camping! I am planning a nice long walk in the woods to decompress from the hectic days of working.' 'I am too. I've been thinking of this since COVID. I hear we have some materials to share between the two of us. What are you thinking? For me, I am from the South so I get cold easily 🙂 so firewood is my main priority.'
Utterance: 'Perfect! I'm a northerner, so the firewood is all yours! I'll need lot's of water to keep hydrated after the hike, and I'll probably be pretty hungry too.'
Solution: Yes
