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: 'yes. I will definitely give you. I bring extra woods.' 'Great! Can I take 2 and you can have 1?? I am willing to give you 2 of the water then!' 'Its pleasure to me. Will you give food extra 1 to me?'
Utterance: 'I suppose I could do that. I am worried a disease has possibly spread to the area due to the very wet weather, but I can sure fish for most of my food then!'

SOLUTION: Yes

PROBLEM: Context: 'hello'
Utterance: 'hi'

SOLUTION: No

PROBLEM: Context: 'Yes. Can you help me to give some extra fodd?' 'I am willing to give you the good, though it would help us--we have a large group.  I really would like to take the water.  We are camping out in a primitive campsite with no running water.' 'Ya sure. '
Utterance: 'Sorry for the type--I meant 'food' not 'good'.🙂'

SOLUTION:
No
