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: 'That would be fun! I feel like I always do better when I have someone to run against.  Competition does me good. That sounds fantastic on the fire wood and water split.  What is your food situation looking like??' 'How about this? 2 for you and 1 for me. Going low carb and mostly brought my own. What do you think? ' 'That sounds great! I don't think my chances for catching any fish are pretty slim!'
Utterance: 'You fish? Perhaps I could learn. Never got into it. '

SOLUTION: No

PROBLEM: Context: 'That's so nice of you! I would be delighted to have some great meals during this camping vacay. 🙂🙂' 'I have managed to bring pouches of some of my favorite seasonings.  I'm hoping to find some great wild mushrooms in the forest too.  ' 'I'm a big fan of well seasoned food and mushrooms! Mmm.. 🙂 Do you think it would also be alright for me to have 2 of the 3 waters since I will be hiking a lot?'
Utterance: 'That would be fine.  I was hoping to have 2 but since I am only walking and you are doing more heavy duty hiking, you take them.  Agreed?'

SOLUTION: Yes

PROBLEM: Context: 'Understood! My top two priorities are food and water! Am hoping we can reach a compromise on the items so that we're both happy!' 'That sounds great, I'm the most flexible on food. How many of the extra packages of food do you want?' 'I am hoping to receive 2 packages of food so that way you also have 1. '
Utterance: 'That sounds great to me. I'm hoping to get 2 firewood, 1 water, and 1 food out of the deal. I'm amicable to more discussion though.'

SOLUTION:
No
