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: 'Well, I'm kind of low on water, so I'd like to get as much of that as I can. I'd like to go hiking and I don't really have enough water for a long trip. What about you?' 'Ohh nice.I also have the same issue around here.The thirst for water is growing high than ever due to drought' 'Well, that's a bummer. How are you set for food? While I wouldn't mind a bit more, I'm in pretty good shape there, so I'd be willing to trade it for water. I'd hate to leave without getting a good hike in.'
Utterance: 'Hun,It's a bit of a fair deal,but due to the condition here i will need a bit more of water though foo cannot be overlooked also for survival but still to survive we take chances.So do you mind me giving you a package of food and u trading 2 pakages of water?.'

Answer: Yes


Question: Context: 'hy thats my offer'
Utterance: 'Hi there.. I'm sorry, I didn't see your offer as it doesn't show it for 10 messages, I believe.  So, here's the situation.. I think I can get by with less firewood as I'm a Floridian and prefer it cooler anyway.. also the food is not a huge thing for me as we can catch / improvise around the campsite - but I'm definitely interested in as much water as possible.. both for cooking and cleaning purposes, as well as drinking, of course.  🙂'

Answer: Yes


Question: Context: 'I'd be fine with taking less food.  So, I would get 3 firewood, 1 food, and 0 water.  Is that correct?' 'And I would get 0 firewood, 2 food and 3 water. That seems right to me.' 'That'
Utterance: 'It looks like we have to continue this conversation beyond a certain point before we come to a deal, so - what is your most cherished camping memory?'

Answer:
No
