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: 'Great thank you. I am looking for primarily some firewood and food for my camping trip soon. ' 'I'm going camping too and also need food and wood, mostly food though' 'Okay I understand that! Is there a particular reason that you do not need much water?'
Utterance: 'I figure I could always get some at the stream 🙂'

Answer: Yes


Question: Context: 'I agree, it will be tricky to find extra food while camping. I'm sure we can figure out something that works for both of us... the water is also very important to me because it's supposed to be hot. There is plenty of wood where I'm going, so you can have the firewood. Would you be willing to take 3 firewood, 1 food and 1 food?' 'I would like at least 2 food, how does me getting 2 food, 1 water,2 firewood sound?' 'I think I can only give away 2 food if you are willing to give up all of the water. How about you take 2 food and 2 firewood? '
Utterance: 'I think that sounds reasonable, i dont get too thirsty!'

Answer: Yes


Question: Context: 'I would need water the most as I forgot to bring enough. I can give you all my food for all of you water, if you'd like?' 'That would be amazing! So I could take all 3 packages of the food and you could have all 3 packages of the water. Now, we just need to split the firewood. Could I take 2 of the firewood leaving you with 1? I think I would need more for cooking the food. ' 'Awesome! That does sound like a deal. I wish we had more firewood to split because I am afraid it might get cold.'
Utterance: 'I agree. I am feeling generous and I did buy a new axe for this camping trip. So, I could stick to the prior agreement and just work a little harder to find some dry trees to chop.'

Answer:
Yes
