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.

Q: Context: 'I am too.  I am so looking forward to this.  ' '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.☹️'
Utterance: '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. 🙂'

A: Yes

Q: Context: 'I know how to filter water so you can have all of the water. I would like as much firewood as possible.' 'me too. I don't care about water since we are camping near a river.' 'I would consider giving you all food and water if I could get all of the wood.'
Utterance: 'Oh really? I think I am able to do it without firewood then. The kids will be full and probably won't ask for smores'

A: Yes

Q: Context: 'How nice. I am bringing my daughter and her girl scout troop. I am the co leader.' 'Oh that' 'We will need some extra water for all the girls on the hike.'
