TASK 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.
PROBLEM: Context: 'I was more thinking 2 Firewood for me , 1 food and 1 water? The rest would be yours.' 'That is a promising bargain but I want at least 2 firewood, it makes for a fun time for my group.' 'Interesting , because my group feels the same way though. How does your group feel about water though?'
