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: 'Hello, I would really like more food for my trip. If I can have all the food, and firewood, you can have all the water' 'Oh, that won't really work for me.  I was hoping to get extra food and water for this trip since I need water to take medication and would love the food to plan a special meal.  I'd like say, 2 food, 3 water and 1 firewood' 'I could give you 2 food, if I could have 3 firewood and 2 water'
Utterance: 'Hmm, how about I take 2 food and 2 water and you can have all the firewood?'
No

Context: 'How many of each supply would you like? what is your favorite?' 'I am flexible, but I would prefer some food and firewood.  I have a large family to feed and all of my food needs to be cooked.' 'I also would prefer some food but am willing to give 3 fire wood in exchange for 3 water. I suffer from chronic dehydration because I sweat too much.'
Utterance: 'Excellent, I would love to help you out.  We have plenty of water to spare.  I'd gladly give you 3 water in exchange for 3 firewood.'
Yes

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.

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.'
