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: ' The item I need the most is water because I need to hydrate to stay strong and achieve my goals. And you?' 'I would say water as well because I am very active and build up thirst as a result.  However, I would be willing to compromise on things to allow you to have more water.' 'The item that I need the least is firewood because I will dedicate myself to look it up at the camp. And you?'
Utterance: 'Yes I think we have the same preferences.  I do not get cold easily and will bring a heavy sleeping bag.  '

SOLUTION: Yes

PROBLEM: Context: 'Ya so I could use a lot of water! Would you be willing for me to take one food two water and two firewood? ' 'Since we will have so much food to cook we could probably use the extra firewood too,would you be ok with me taking 2 food and 1 water and 2 firewood?🙂' 'No I'm giving you two of your top items I think it's only fair I get more items. '
Utterance: 'ok, that does make sense. I would agree to that. 🙂'

SOLUTION: No

PROBLEM: Context: 'Hmm, ok, thats pretty fair. I do have a larger group going as well, so would it be okay if I got 2 extra food then?' 'I think that will work. ' 'Ok, great!🙂 Just to recap, I'll get 2 water, 0 firewood, 2 food, you get the rest.'
Utterance: 'That's right.  Thanks for making this part of planning for the trip easy'

SOLUTION:
No
