Definition: 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 am doing well, thanks! ' 'That's good to hear. I am going camping this weekend and need some extra supplies. What about you?' 'That's great! I also have a comping trip planned. We will be having an all night dance party. I could definitely use some extra supplies. What are you in need of the most?'
Utterance: 'That sounds like fun. I am pretty good at hunting and fishing, so I really don't need the extra food. I would like some extra firewood however. That would help cook the food and keep animals and insects away at night'
Output:
Yes
