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.

Question: Context: 'I am doing well, how about you? It is another hot July day.' 'I am doing pretty good. I am going camping this weekend and just double checking to see what extra supplies I need' 'I love camping, have not gone in a while. Have you ever camped by a lake?'
Utterance: 'Yeah! I usually camp by the lake so I can use the lake water when I need extra water.'

Answer: Yes


Question: Context: 'Ok, let me then give you 2 packages of firewood and 2 packages of water and you give me 2 packages of food. What about that?' 'So I get 1 food, 2 water and 2 firewood?' 'What is your take?'
Utterance: 'And you will get 2 food, 1 water and 1 firewood? I think it is a great deal since food is hard to find in the camp site. I don't think you want to go hunting🙂'

Answer: No


Question: Context: 'Let's be reasonable here. If you are nice to me I'll be nice to you. I'll take the majority of the wood and food if you want most water.' 'Again don't patronize me.  What is your main focus?' 'Please grow up. No one is patronizing you. I'm trying to negotiate. Don't be so emotional okay?'
Utterance: 'Grow up. 🙂 This was too easy.  Now please answer the question.'

Answer:
No
