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: 'Okay so we can think about splitting the firewood. 🙂 I'm also interested in water because I plan to do a lot of activities like hiking and kayaking, so it will be helpful for me to be able to hydrate more.' 'That is okay. What about i get 2 packages of firewood and then you get 2 packages of water. Is that okay with you?' 'Since I'm most interested in firewood, I would want 3 waters if you're going to get more firewood.'
Utterance: 'Nice. That's okay with me. You get 3 waters and a I get 3 firewood'
No

Context: 'Ya definitely. I need food and firewood most. What do you need?' 'I believe that we have the same priorities. So we have a large family including children that need the food, but my wife also needs firewood due to poor circulation. She is susceptible to frost bite and limb loss' 'Okay so how about one of us takes 2 of the food and 1 of the firewood, and the other takes 1 of the food and 2 of the firewood?'
Utterance: 'that sounds fair. I will take 1 food, 2 firewood, and 2 water, thus giving you 2 food, 1 firewood, 1 water'
No

Context: 'you told me i not fair that why i told you are not fare,3 food for me will give 3 firewood for me, give 2 water for me, other we can end the deal and both we can forget the bonus' 'ok' 'then what will do ? if you ok for 3 food for me , 3 firefor you, 2 water for me , for this deal we can go forward?'
Utterance: 'of course not. you just took all the priority items and you still want two water. I am going to make the last offer. you take two food and two water, I take one food, three wood and aone water. '
No
