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.

Ex Input:
Context: 'I could give you 1 water for 1 firewood, most of my firewood got wet so is almost useless . Would you perhaps except some food for another unit of firewood?' 'Oh. Let do some deal. If you give me all water bottles I will give you 2 firewood. Can you accept this' 'i could give you 2 water bottles and 3 food if you can do 3 firewood'
Utterance: 'OK. Are you need Extra food packages?'

Ex Output:
No


Ex Input:
Context: 'I don't mind the division but I would like a pack of firewood added because my family of 7 consume this item as well during the day & night' 'you would have to give more items up to get firewood. if you get more water, which is our highest item, i need more of other items' 'How about 1 water, 2 food and 2 firewood?'
Utterance: 'I don't really need food, to be honest. Food is the least of my worries.'

Ex Output:
Yes


Ex Input:
Context: 'I would be most happy to make a concession on the food for an extra ration of water.
