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: 'Same here. I'll go ahead and list some of what I need and you let me know if you will need the same as well. I need some extra water for our camping trip as well as some additional food. ' 'That sounds reasonable. I don't particularly need the food because I see that as more of a luxury but I could really use some more water. It's supposed to get really really hot on the weekend. 😮' 'I hear that. What do you think of if I take 3 of the food supplies and you can have two waters? '
Utterance: 'That sounds like a fair compromise. I can get food by hunting animals, old school style. That would give you 4 total items. In that case it's only fair if I take all 3 of the firewood. 4 for me and 4 for you sounds like a good deal to me. 🙂'

Output: Yes


Input: Consider Input: Context: 'I was hoping to pick up a lot of wood. It has rained around here and the wood is soggy in the forest.' 'Which item do you prefer the most?' 'I know how to filter water so you can have all of the water. I would like as much firewood as possible.'
Utterance: 'me too. I don't care about water since we are camping near a river.'

Output: Yes


Input: Consider Input: Context: 'We want to hike along the trails near the river! We will need lots of food to keep us going ' 'I understand that atleast you are going to be close to water, that will be our most important thing since we will be thirsty and you know kids and trying to tell them to ration the water...LOL' 'for sure thats not going to work to well '
Utterance: 'are you hiking alone?'


Output: No
