Part 1. Definition
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.
Part 2. Example
Context: 'That sounds pretty reasonable as I am in need of firewood the most. Would it be most reasonable to each take what we need most and split the water down the middle?' 'Yes, it would.' 'I think that sounds fair. The problem is that there are 3 waters and one of us would get two and the other one. How should we sort that?'
Utterance: 'You can take the two water. I am not that thirsty most days.'
Answer: No
Explanation: In this utterance, the participant does not use self-need since they do not talk about any need for themselves.
Part 3. Exercise
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?'
Utterance: 'Thanks. Yea they do  love their snacks LOL. Yea I just need 1 extra food. Snice I wasn't planning on her friend coming. '
Answer:
No
