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.

[Q]: Context: 'It's nice to know the firewood is not important to your camping trip. I'm glad I can have all the firewood to myself. How do we get to share the other resources. ' 'Actually, I think I may need more food than water. How about I take the food and we can split the water. You may have 2 waters, if you need them.' 'Sure then. You can take all the food. It's not really a priority to me. '
Utterance: 'Great. So if I have three food and one water, you can have three firewood and two water. Would that work for your trip?'
[A]: No


[Q]: Context: 'Hmmm.  And the firewood?' 'I get cold easily. I need the firewood to get warm. I might catch a cold.🙂' 'I think water should be your priority.  You have food and firewood also in your basics.  I will let you have the 3 water but I will need the 3 Firewood and the 3 Food.  I have a medical condition.'
Utterance: 'Okay that works well. I accept! 🙂'
[A]: No


[Q]: Context: 'What about you take 1 water and the firewood.  I take 2 waters and all the food' 'That leaves me with very little. Can I have 1 water, 2 firewood, and 2 food?' 'you would get 1 water and all 3 firewood.  I would get 2 water and all 3 food.  You have one less than me but the food is worth less'
Utterance: 'I will make it work. Let's make a deal!'
[A]:
No
