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.

Context: 'Hello, I am very cold and need food and wood to remain warm. How about I get 3 firewood, 3 food and 1 water?' 'That doesn't really work for me because then I would get only 2 waters and nothing else ☹️. What do you think is your highest priority?' 'Wood is my highest priority. I need it to stay warm. I'm very cold-natured. What is your highest priority? 🙂'
Utterance: 'Oh that's good. Wood is not my highest priority since I get hot easily lol. My highest priority is probably food because I have a very high metabolism and get very hungry'
Yes

Context: 'Hello hood to see a fellow camper.  How are you doing today?🙂'
Utterance: 'Hey! I'm doing great, how are you? '
No

Context: 'So I get 3 food and 2 firewood? And you get all of the water?' 'yes does that sound good to you?' 'Yes, I am happy with that arrangement. '
Utterance: 'Alright so let us finalize'

No
