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.

Utterance: 'Oh no! That's unfortunate! Luckily, I think I have plenty of Firewood for myself so I think it would be okay for you to have more of that if needed. I don't know if I have enough food. I love to snack all day!'

I will say it has really sparked my interest in camping and being outdoors even more though! I saw just how connected I was to technology and everything else!' 'I'm up here to do some cross training and noticed that there is some extra water around. Even though the nights are cold I could use some extra water. Do you exercise much?'
Utterance: 'It has been extremely dry in the area I will be going to so I was hoping to get a little extra water too.  I do. I love hiking and running trails!  Due to the extreme dry weather I should have plenty of wood I can scavenge for if you need all of it!'


Output: Yes
