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 would be most happy to make a concession on the food for an extra ration of water. Are you going to require any firewood if you don't need any I think i'll take the 3 rations so I can have a nice bonfire.' 'I do believe I would need at least one firewood, but am willing to give up 2, so you can have a nice big bonfire 🙂' 'You have been most thoughtful during this negotiation I just want to say thank you for being so helpful.🙂'
Utterance: 'absolutly! You as well. So just to confirm. Me 2 food 1 water, 1 firewood. You, 1 food, 2 water, and 2 firewood? Sound good?'
answer:
No


question:
Context: 'Okay so would 2 firewood for you and 1 for me work, and 2 food for me and 1 for you?' 'I can definitely agree to that.  What was your second preference?  Water was my third.' 'firewood is my second preference and water is my third'
Utterance: 'Well, water doesn't benefit either of us much, so you can have two. So you will take 2 food, 1 firewood and 2 water?'
answer:
Yes


question:
Context: 'Food is the item of greatest value to you?' 'It is! What do you think?' 'The item of greatest value to me is WATER. Before thinking about an offer I need to know what your priorities are and you need to know mine in order to conclude something fair for both of you.'
Utterance: 'My priority is FOOD. How about I get 3 food and you get 3 water?'
answer:

No
