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.

Input: Consider Input: Context: 'Hello, I hope we can work together on an offer that benefits both of us. Do you think it's OK?🙂' 'Yes definitely!  I am pretty easy to work with and would like a deal that will help us both out as much as possible.' ' The item I need the most is water because I need to hydrate to stay strong and achieve my goals. And you?'
Utterance: 'I would say water as well because I am very active and build up thirst as a result.  However, I would be willing to compromise on things to allow you to have more water.'

Output: No


Input: Consider Input: Context: 'Well, we have extra food too. How about I take 2 water, 1 food, and give the res (1 water, 2 food, 3 firewood) to you?' 'That's super thoughtful of you. However, I really need two waters so I can provide for everyone. Once we have enough food and fire we can always go get water from the stream and boil it for the kids.' 'Of course there is no garuntee you will catch anything, if you want 2 waters I'd prefer to take all the food just in case'
Utterance: 'I would certainly give you all of the food if I could have 2 waters and 1 firewood.'

Output: No


Input: Consider Input: Context: 'Actually, I'd like to keep some water as well in case it gets so cold that the lakes and other water sources freeze.' 'Well, I need as much food as possible. You seem to want firewood. How about you suggest something.' 'That's a good idea.Let me think. How about 3 Firewood, 1 Food and 2 waters for me.'
Utterance: 'That will not work for me at all. '


Output: No
