instruction:
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 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?'
Utterance: 'Water is not that important for us but the firewood is a deal breaker for us ☹️'
answer:
Yes

question:
Context: 'I don't like food. my stomach is always full. I only drink water since im thirsty most of the time.' 'yeah i can understand buddy, but the fact is we can share some items. you are not getting food packages and getting packages alone which you preferred. Try some food packages too' 'Okay I agree what about this deal. I get 2 water, 1 firewood ,and 1 food package.'
Utterance: 'sounds good. but how much firewood will i get ? because i don't need it much'
answer:
Yes

question:
Context: 'Hi, 🙂 It's nice to meet you as well: I also hope we can work something out: Food is my excess trip priority, What is yours?' 'Mine is firewood with second being food.' 'I'm definitely willing to give up some food for some firewood: That seems like a place where we can come to an arrangement: Would you like to make an opening offer? '
Utterance: 'Sure! I figure I can go with little water as we can get it from the stream and boil it. So for water I would be willing to give you 2 packages. Would that be fair?'
answer:
Yes
