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.

Ex Input:
Context: 'That sounds fair to me! So we've got 2 water and 2 firewood for you, 3 food and 1 each water and firewood for me.' 'Yes, you're very kind. I desperately need some more water and firewood.' 'I'm glad we were able to work out something for both of us! I hope you have a great camping trip!'
Utterance: 'Sorry, just adjusting the numbers to what we agreed above! '

Ex Output:
No


Ex Input:
Context: 'So why did you decide to come camping?🙂' 'I think it will be fun. I was wondering what your preferences are for the extra items we can bring?' 'I was hoping for food as I forgot a bag at of stuff at home. I also was hoping to star gaze but I may not have enough wood to keep warm.'
Utterance: 'I understand. I too would really like some food because I would get pretty hungry without it and I also forgot to bring some. Firewood is so important for keeping warm. There are three of each item. Maybe we can negotiate on how to split the resources'

Ex Output:
Yes


Ex Input:
