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 self-need strategy, otherwise output No. self-need is a selfish negotiation strategy. It is used to create a personal need for an item in the negotiation, such as by pointing out that the participant sweats a lot to show preference towards water packages.

Input: Consider Input: Context: 'Oh no! I hope you are okay! ' 'Yeah, I'm okay now.  It's just that I need to have a lot of food around to be able to manage it properly.  Like on this camping trip.' 'I totally understand! I am in need of food too, but it sounds like you really need it so I am hapy to give you all of the food if I can have all of the firewood?'
Utterance: 'What is your need for water?  I could use some of that, too.'

Output: No


Input: Consider Input: Context: 'Great thank you. I am looking for primarily some firewood and food for my camping trip soon. ' 'I'm going camping too and also need food and wood, mostly food though' 'Okay I understand that! Is there a particular reason that you do not need much water?'
Utterance: 'I figure I could always get some at the stream 🙂'

Output: No


Input: Consider Input: Context: 'I get tired to easy so I probably won't be much fun at a bonfire ☹️. I really do appreciate the offer though. I would think the extra food would do you more good for your party. ' 'The extra food would be appreciated.  How about if I take just two each of the firewood and food, and you can have the remainder, plus all of the water?' 'I am just concerned that only 1 firewood might make it so I'm too cold to function. '
Utterance: 'If you boil the water above the fire, it will provide additional heat over time.  You would also be able to make tea, which would warm you up from the inside as well, better than any fire would.  That would probably be most beneficial to you.  I really do need the 2 firewood if there's any chance of making a bonfire for my party.'


Output: Yes
