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.

Context: 'Hi, I brought some water with me. How much do you need? '
Utterance: 'I want 2 liters of water'
No

Context: 'Hello, great to see a fellow camper.  Planing on doing any hikes.  My family and mother-in-law are down getting some new trail maps.  We are looking forward to the long camping weekend.  Our bad luck was the airline loss two of our bags that had our food and water.  So i am hoping to get some more.🙂'
Utterance: 'Hello! Thats terrible that the airline lost your bags! I'm planning on have a large group of friends with me so we need lots of snacks with us. We are scared of fires so we don't want to make campfires.'
Yes

Context: 'I'm sorry about that, accidentally hit that send button lol! I was thinking about it as well. I'm pretty excited. How about you?' 'I was just thinking about the logistics and how to prioritize the various items.' 'Same here. I'll go ahead and list some of what I need and you let me know if you will need the same as well. I need some extra water for our camping trip as well as some additional food. '
Utterance: 'That sounds reasonable. I don't particularly need the food because I see that as more of a luxury but I could really use some more water. It's supposed to get really really hot on the weekend. 😮'

Yes
