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: 'How are you today? Did you have any preferences on the supplies we will be trading?' 'I am good. How about yourself? I think I would like some firewood to start off with. We like to have bigger fires. What about you?' 'I am good as well. That is good to hear that you like to have bigger fires as we do not care much for that. We would much rather have some extra water.'
Utterance: 'Water is a little important to us too though , if possible maybe we can split that or maybe we can get some more food in replacement.'

Ex Output:
No


Ex Input:
Context: 'Hmm, okay, that sounds reasonable. How does 3 water, 2 food and 1 firewood for me, and all the rest for you sound?' 'Im goign to need all the firewood I can get. They want to cook smores on it. How about you get 3 water 2 food and I get 3 firewood and 1 food. I think that is very fair and would help us both out. 🙂🙂' 'That sounds like a very reasonable deal, I understand how girls can get with their snacks haha. I'm okay with giving up all the firewood. You said you need at least some of the food, right?'
