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.

Question: Context: 'Hi! How is your camping trip going?' 'It's going good we could use some more supplies such as food and firewood, though.' 'Same here haha. Is water your lowest priority item too?'
Utterance: 'Yes. We think we have enough water for now.'

Answer: Yes


Question: Context: '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.' 'My spouse calls me a water buffalo so I'm pretty water dependent if you couldn't tell.  ' 'That's good.  Best way to stay healthy is with water.  How about you take 1 water and all the firewood?'
Utterance: 'I need at least one ration of food.  Would it be ok with me:  3 firewood and 1 each of food and water.  If you are ok with that, I am too.'

Answer: No


Question: Context: 'Of course! Are you going camping too?' 'Yes.  I have 2 children so I was thinking that I will need extra water. 🙂' 'I too need extra water, but I'm willing to negotiate on the other things if you are! 🙂'
Utterance: 'If I take 2 waters, will you accept 2 firewood?'

Answer:
No
