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: 'I am doing well, thanks! ' 'That's good to hear. I am going camping this weekend and need some extra supplies. What about you?' 'That's great! I also have a comping trip planned. We will be having an all night dance party. I could definitely use some extra supplies. What are you in need of the most?'
Utterance: 'That sounds like fun. I am pretty good at hunting and fishing, so I really don't need the extra food. I would like some extra firewood however. That would help cook the food and keep animals and insects away at night'

SOLUTION: Yes

PROBLEM: Context: 'I have a medical condition that causes my veins to close up when I get too cold. I will thus need the 3 firewood.' '☹️Oh, that sounds awful. Are you sure you need all three packages of firewood?'
Utterance: 'I might be able to get by with just two... I'm on a diet though, so I don't need as much food.'

SOLUTION: Yes

PROBLEM: Context: 'yeah you are right, but water is essential for all !☹️, you must consider that too' 'I agree water is needed. I can do 2 water 2 firewood and 0 food' 'you consider me giving one of your water package and collect food package, if you are lucky you can get liquid foods too🙂'
Utterance: 'I don't like food. my stomach is always full. I only drink water since im thirsty most of the time.'

SOLUTION:
Yes
