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: 'Yes! I am so on the same page as you. I want to be sure I'm set and prepared. 🙂' 'Would you consider letting me have 2 of the 3 extra firewood?  I have health issues and I get really cold sometimes.☹️' 'Yes, I think that would be very fair, since I don't have health issues myself. Would you allow me to have 2 of the 3 food items? I need energy for hiking. 🙂'
Utterance: 'That would be perfect.  I am a gourmet cook and if you would like me to help you prepare the evening meal, I would be very happy too.🙂'

Answer: Yes


Question: Context: 'Ok so I propose 2 water for me, 1 for you. 2 food for you, 1 for me. Firewood would be, 2 for you, 1 for me? Please give me your opinion if you want to reverse any of that.' 'That would work, the extra firewood would offset the need to have water on hand when I can boil it.' 'Just take one more minute to make sure you are good with that and let me know. As soon as you are absolutely sure, I will send the proposal.'
Utterance: 'You need the water more I feel. I don't want to slight you for having a medical condition and I know how the heat can take a toll on people. I think that proposal works well enough as I'm getting extra firewood and food. '

Answer: No


Question: Context: 'Oh. Let do some deal. If you give me all water bottles I will give you 2 firewood. Can you accept this' 'i could give you 2 water bottles and 3 food if you can do 3 firewood' 'OK. Are you need Extra food packages?'
Utterance: 'no, I am okay with food which is why I offered them all to you since all my firewood is ruined. I figured if i gave you 2 water and 3 food you might be able to spare the 3 firewood'

Answer:
Yes
