Instructions: 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.
Input: Context: 'I get really cold at night so I'd like to have extra firewood. ' 'Same. Plus I am planning on keeping a fire long into the night. Eating alot of food also helps keep you warm while sleeping. Perhaps I could offer you some extra food in return for some extra firewood?' 'Hmm I will have to think about this offer. How do you feel about the water packages?'
Utterance: 'I am a water junkie day to day but the place I am camping as a stream and I'm taking my water filter system, so I could offer you extra water in this case.'
Output:
Yes
