TASK DEFINITION: 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.
PROBLEM: Context: 'Hi there, good to connect with you. How are you today?' 'I am good, thank you. What are your preferences? I really need the extra food packages. We are doing a lot of hiking and mountain biking and there are no grocery stores for at least 50 miles.🙂' 'Oh wow that is quite a lot of hiking! I think we will be hanging out a lot overnight and so I am looking for more firewood if possible. My kids can't hike very far and want to do more with smores and marshmellows. '
Utterance: 'I can work with that. I am willing to give you all of the firewood. We are in a hot climate and won't need too much. Being in a hot climate and with a lot of exercise, I am hoping to take the three water packages. '

SOLUTION: Yes

PROBLEM: Context: 'What are your preferences? I always love having a big fire at night when I am camping and I do think water is more important than food.'
Utterance: 'I like to have a lot of food to keep my energy up, but I might need some firewood to cook that food. I can't wait for my camping trip.🙂'

SOLUTION: No

PROBLEM: Context: 'Howdy! How are you?' 'I am dong just fine! and you?' 'Pretty good! I am excited about going camping though. When we split this, what do you need the most?'
Utterance: 'We are all about the food over here! what about you?'

SOLUTION:
No
