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: 'I was thinking maybe I could have a majority of the fire food and you can have a majority of the water and food. ' 'What exactly do you mean by majority? As in everything ?' 'I was more thinking 2 Firewood for me , 1 food and 1 water? The rest would be yours.'
Utterance: 'That is a promising bargain but I want at least 2 firewood, it makes for a fun time for my group.'

Answer: No


Question: Context: 'That sounds reasonable. I don't particularly need the food because I see that as more of a luxury but I could really use some more water. It's supposed to get really really hot on the weekend. 😮' 'I hear that. What do you think of if I take 3 of the food supplies and you can have two waters? ' 'That sounds like a fair compromise. I can get food by hunting animals, old school style. That would give you 4 total items. In that case it's only fair if I take all 3 of the firewood. 4 for me and 4 for you sounds like a good deal to me. 🙂'
Utterance: 'That sounds fair to me! I don't know the first thing about hunting so that would be a relief on me. We took a bunch of blankets so we'll be good on firewood.  🙂'

Answer: Yes
