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.

Ex Input:
Context: 'I'm thinking I'l get 2 firewood, and 2 water and 1 food. I'm not sure what you need, but we can figure it out. ' 'my highest priority is water, i need it to stay hydrated from the camping beers' 'Who doesn't? I need more wood. I'm skinny. I get cold easily. Beer hidrates dude 🙂'

Ex Input:
Context: 'Yah we have a few things planned. One of the things they are looking forward to is reading scary stories by the campfire and making s'mores' 'That sounds like a lot of fun. What do you think you will need for that experience?' 'We likely need a lot of firewood and some water to put out the fire when we are done lol. What are you thinking?'
Utterance: 'Yea, I'm not too into firewood because it will be quite hot when I make my camping trip. I could definitely use some more food just in case of an emergency out there.'

Yes
