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.

Ex Input:
Context: 'What type of place are you thinking of going camping to? Like what is the climate/area? More desert or forest, etc?' 'Forest, for sure. Deserts have scorpions and tarantulas and I'm scared of those.' 'Amen! Me too! 🙂 I too was thinking of going to the forest. Is your forest going to be wet or pretty dry?'
Utterance: 'It'll be pretty dry. I don't want to catch a cold. '

Ex Output:
No

Ex Input:
Context: 'That is awesome! The one bad thing about my campsite is there's no stream or lake nearby. I'm going to need a lot of it so I can shower/wash up' 'Well I was hoping to grab some extra water as well, Its suppose to be record highs. ' 'I'm sure we can figure something out. I'm going to need a good amount of firewood too to cook my food. The good news is I won't need any food 🙂'
Utterance: 'Well I'm not interested in any firewood, I already have plenty, I do need extra food however'
