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: 'Yes! I am so on the same page as you. I want to be sure I'm set and prepared. 🙂' 'Would you consider letting me have 2 of the 3 extra firewood?  I have health issues and I get really cold sometimes.☹️' 'Yes, I think that would be very fair, since I don't have health issues myself. Would you allow me to have 2 of the 3 food items? I need energy for hiking. 🙂'
Utterance: 'That would be perfect.  I am a gourmet cook and if you would like me to help you prepare the evening meal, I would be very happy too.🙂'

Output: Yes


Input: Consider Input: Context: 'hy thats my offer'
Utterance: 'Hi there.. I'm sorry, I didn't see your offer as it doesn't show it for 10 messages, I believe.  So, here's the situation.. I think I can get by with less firewood as I'm a Floridian and prefer it cooler anyway.. also the food is not a huge thing for me as we can catch / improvise around the campsite - but I'm definitely interested in as much water as possible.. both for cooking and cleaning purposes, as well as drinking, of course.  🙂'

Output: Yes


Input: Consider Input: Context: 'Hello. ' 'Hi! How are you doing today?'
